RF Antennas

Rf Antennas covers the parts that get a wireless signal in and out of your board: chip antennas, PCB trace antennas, flex and FPC antennas, external whip and puck antennas, and embedded modules for sub-GHz, 2.4GHz, GNSS, LTE and Wi-Fi bands. They show up everywhere, from handheld meters and asset trackers to gateways, smart meters, automotive telematics and industrial sensors. The category looks simple on paper, but sourcing is rarely just about price. Engineers usually care about matching and return loss in the real enclosure, not just the datasheet peak gain. A 2dB difference on paper can disappear once the antenna is squeezed next to a battery and a metal shield. Buyers also check the feed type, connector (U.FL, SMA, MMCX), cable length, mounting style and whether the part is tuned for the exact band plan of the target region, since an LTE antenna that works fine in Europe may underperform on a North American carrier. On the procurement side, the common trade-off is lead time versus flexibility. Popular chip antennas from Murata, Johanson or Taoglas are usually stocked, but a specific whip antenna with the right connector and radome color can carry an 8 to 12 week factory lead, so many teams qualify two sources early. Counterfeit risk is lower than with high-value ICs, though repackaged or off-spec cable assemblies do circulate in the gray market, which is why lot traceability and original packaging matter. MOQ is another practical point: chip antennas often come on reels of 1,000 or more, while external antennas may be sold piece by piece.
