Antenna wifi ble gnss lte coverage in Walsin’s export is thinner than the product names suggest. We searched all 44 rows: 12 name a standard, in the words “BT, Wifi”. GNSS, GPS, LTE and BLE appear on none. Of those 12 chip antennas, 2 state a 5 GHz band.
Venatech Limited, an authorised Walsin distributor in Hong Kong, read every cell of the antenna export published by Walsin Technology (Walsin): 44 part numbers and 10 columns. This post asks a different question from our earlier antenna work on band strings and units. It asks which standards a buyer is told a part serves, and whether the stated frequency range backs that up. Every part number below is real. We hold no antenna datasheet, so the export is the only source.
Which wireless standards does the Walsin antenna export actually name?
Two words, on one series. We searched all 440 cells in the 44 rows for 22 standard and protocol terms. “Wifi” and “BT” each appear on 12 rows, all in the series label “Chip Antenna (BT, Wifi BAND)”. NFC and WPC appear once each, as series names. GNSS, GPS, LTE, BLE, Bluetooth, Wi-Fi, Zigbee, LoRa and cellular appear on zero rows.
| Term searched | Rows containing it | Where it appears | Match / mismatch against what a buyer searches for |
|---|---|---|---|
| Wifi | 12 | series label of the 12 chip antennas | Match on the word, mismatch on spelling — the common spelling is Wi-Fi, which matches 0 rows |
| BT | 12 | the same 12 labels | Mismatch — “Bluetooth” matches 0 rows and “BLE” matches 0 rows |
| NFC | 1 | series name of RFNFC355500NNNB001 |
Match |
| WPC | 1 | series name of RFWPC483246NNPBC01 |
Match on the code, mismatch on meaning — the export does not expand it |
| GNSS, GPS, GLONASS, Galileo, BeiDou | 0 | nowhere | Mismatch — the satellite parts carry only a frequency |
| LTE, 5G, NB-IoT, cellular | 0 | nowhere | Mismatch — the cellular-range parts carry only frequencies |
We have not seen this counted anywhere. A text search for the protocol you design for finds Walsin’s chip antennas for two of them and nothing for the rest. The other 32 rows say what they cover only in megahertz. See also how the frequency strings themselves are written in our count of 22 spellings.
How many Walsin antennas state a band that covers each standard?
Twenty-four of the 38 antennas state a span that holds one of the bands we tested, and 14 hold none. We excluded the 6 cable assemblies and connectors, split every dual-band cell and tested each antenna’s stated span against reference bands. 22 contain the 2.4 to 2.5 GHz band, 6 contain 5.15 to 5.85 GHz, 2 contain the GNSS L1 centre and 0 contain Walsin’s own 698 to 2690 MHz cellular-width coupler band.
| Reference band | Source of the span | Antennas whose stated span contains it | Stated as a spot or 5.x, untestable |
Example part | Match / mismatch against a filter on the stated range |
|---|---|---|---|---|---|
| 2.4 to 2.5 GHz | Walsin’s own string | 22 | 3 | RFANT3216120A1T |
Match — 22 of 25 antennas that mention 2.4 GHz |
| 5.15 to 5.85 GHz | Walsin’s own string on 4 parts | 6 | 3 | RFPCA430805IMLB301 |
Match on 6; mismatch on 3 that say 5.x |
| GNSS L1 centre | outside figure, see note | 2 | 1 | RFFPA401410IMGB301 |
Match on 2; the third states 1.575 GHz |
| 698 to 2690 MHz | Walsin’s coupler string | 0 | 1 | RFDPA131012IMTB301 |
Mismatch — three spot frequencies, no span |
The 14 antennas outside all four tests are not defective. They are 433 MHz, 700 plus or minus 50 MHz, 840 to 868 MHz, 863 to 928 MHz, 880 to 960 MHz, 13.56 MHz and 100 kHz parts, plus spots and wildcards the test cannot read.
Do the 12 chip antennas labelled BT and Wifi cover 5 GHz?
Two of them do. We read the Working Frequency Range cell of all 12. Ten state only 2.4 GHz, one of those out to 2.55 GHz. Two, RFANT6050110L0T and RFANT6050110L1T, add a 4.9 to 5.9 GHz band, so 16.7 percent of the chips carrying the Wifi label state any 5 GHz range.
| Part | Series label | Stated range | Published gain | Match / mismatch against “Wifi means 2.4 and 5 GHz” |
|---|---|---|---|---|
RFANT3216120A1T |
Chip, BT, Wifi | 2.4 to 2.5 GHz | 2 dBi | Mismatch — one band |
RGFRA9937380A3T |
Chip, BT, Wifi | 2.4 to 2.55 GHz | 2 dBi | Mismatch — one band, wider |
RFANT6050110L0T |
Chip, BT, Wifi | 2.4 to 2.5 and 4.9 to 5.9 GHz | 4 dBi, one figure | Match on both bands; mismatch — one gain for two bands |
RFDPA141300SBLB801 |
Dipole, N, SMA | 2.4 to 2.5 and 5.15 to 5.85 GHz | more than 5, more than 6 dBi | Match — gain stated per band |
RFPCA430805IMLB301 |
PCB | 2.4 to 2.5 and 5.15 to 5.85 GHz | more than 3, more than 6 dBi | Match — gain stated per band |
The label is not wrong. It is incomplete for anyone reading “Wifi” as both bands. Across the six antennas that state a 5.15 to 5.85 GHz-containing span, only 3 publish a gain per band; the two chips and RFDPA191315IMLB301 publish a single figure. Three further parts say 5.x GHz with no span at all. Our 2.4 GHz chip antenna guide covers the single-band chips.
What does the export say about GNSS and LTE?
Only frequencies, and three of them look like GNSS. We found no row naming either, so any claim has to be made from the range cell. Two antennas state a span around 1.575 GHz, RFDPA141300SMGB701 at 1565 to 1606 MHz and RFFPA401410IMGB301 at 1559 to 1609 MHz; a third, RFDPA870900SBGB801, states a single 1.575 GHz at 0.44 dBi.
For cellular, no antenna states a continuous span. The nearest is RFDPA131012IMTB301, whose range cell reads 850/1900/2100 MHz. Its VSWR cell holds the only spans in the row, 824~960MHz and 1710~2700 MHz, both at 3.0 or below. Of the other 43 VSWR cells, 34 read a single maximum of 2.0, 2.1 or 2.5, 8 are blank and one, on the 863 to 928 MHz metal antenna, splits by sub-band. That detail is easy to lose. A parser that reads only the range column sees three points; the span lives in the wrong column. No row says LTE, and the export does not map any antenna to a band number. For the sub-GHz side see sub-GHz antenna selection.
How should you screen an antenna against a standard you need?
State the bands you need as spans, then test them against the range cell, not the series label. The label named a standard on 12 rows; the range cell states a true span on 27 of 38. Leave the right-hand column for your incumbent part.
| Your requirement | Walsin candidates by stated span | Your incumbent part | Match / mismatch |
|---|---|---|---|
| 2.4 GHz only, smallest | RFANT3216120A1T and 9 other chips |
______ | Check gain 2 dBi, VSWR 2.0 max |
| 2.4 and 5 GHz, chip | RFANT6050110L0T, RFANT6050110L1T |
______ | Check one 4 dBi figure for two bands |
| 2.4 and 5 GHz, per-band gain | RFDPA141300SBLB801, RFPCA430805IMLB301 |
______ | Check form factor; neither is a chip |
| GNSS span | RFFPA401410IMGB301, RFDPA141300SMGB701 |
______ | Check FPC or dipole, not chip |
| Cellular span | none states one | ______ | Mismatch — ask Walsin for the VSWR plot |
Our free cross-reference tool lists differences from your original rather than hiding them. What is in Hong Kong is on ready stock, 1,125 part numbers as at 23 September 2026, a dated snapshot and not a live feed; the antenna range is on the antenna products page. We hold zero antenna datasheets. Confirm against both datasheets and qualify in your own circuit.
The short version
- 44 rows searched: “Wifi” and “BT” on 12, NFC and WPC on 1 each, GNSS, GPS, LTE and BLE on 0.
- 2 of the 12 Wifi-labelled chips state 5 GHz; 10 stop at 2.4 GHz.
- 22 antennas contain 2.4 to 2.5 GHz, 6 contain 5.15 to 5.85 GHz, 2 contain the GNSS L1 centre, 0 contain a cellular-width span.
- The only cellular spans in the file sit in a VSWR cell.
Search the range, not the label. And a question back: if the product name says Wifi and the data says one band, which one did your last design review believe?
Frequently asked questions
Does Walsin list a GNSS antenna?
Not by name. No row among 44 contains GNSS or GPS. Two antennas state a span around 1.575 GHz, 1565 to 1606 MHz and 1559 to 1609 MHz, and a third states a single 1.575 GHz. Judge them from the range cell and confirm the band with Walsin.
Do Walsin chip antennas cover 5 GHz Wi-Fi?
Two of 12 do. RFANT6050110L0T and RFANT6050110L1T state 4.9 to 5.9 GHz as well as 2.4 to 2.5 GHz, at one 4 dBi figure. The other ten chips state 2.4 GHz only, so the Wifi label alone does not tell you.
Is there a Bluetooth Low Energy antenna in the Walsin range?
The export says BT on 12 chip antennas and BLE on none. All 12 state 2.4 to 2.5 GHz, one out to 2.55 GHz. Whether a given part suits your Bluetooth radio is a question for the datasheet, which we do not hold.
Does any Walsin antenna state an LTE band?
No. LTE, 5G and cellular appear on zero rows. The nearest part, RFDPA131012IMTB301, states 850, 1900 and 2100 MHz as spot values and puts spans of 824 to 960 and 1710 to 2700 MHz in its VSWR cell.
How many Walsin antennas support dual-band 2.4 and 5 GHz?
Six state both spans: two chips, three cable or N and SMA dipoles and one PCB antenna. Three more say 5.x GHz without a span. Only three of the six publish gain per band.
Why does the series label say Wifi but the range say one band?
The export does not explain. The label names a use, the range cell states a measurement, and on 10 of 12 chips they cover different ground. Treat the range cell as the specification and confirm with Walsin.
