enter image description hereI'm looking to add an external antenna and I want to find out I add the antenna using a Mini PCI U.FL to RP-SMA Antenna WiFi Cable Signal Connector Network Adapter I got off of ebay to a Trendnet Range Extender. I'm a total newb and need help identifying what #1 is, what #2 is, and really what else I might need to know to get this working. Thanks!!!!![enter image description here]2


1 Answer 1


1 is a ceramic chip antenna (Datasheet/App note for similar/generic chip antenna). Instead of a wire or pcb trace antenna (or some other type), a chip antenna allows a manufacturer to avoid lengthy testing by using a 3rd party dedicated part.

2 looks like a u.fl connector, but the picture is blurry, can't be sure.

Update: Another question has the answer to the connector. It's a switched connector. See the answer to What connector is similar to U.FL but has no pin?

  • \$\begingroup\$ You will likely need to desolder/remove one of the series capacitors between the connector and the chip antenna, but not sure. \$\endgroup\$

  • \$\begingroup\$ It doesn't exactly look like a u.fl connector in the sense that it doesn't appear to be a male. It looks like a female connector of sorts. Added another picture, still blurry but closer up. This may be a dumb question, can i solder the cable i'm getting to the chip, or right next to/touching the chip antenna? \$\endgroup\$

  • \$\begingroup\$ Instead of the chip, yes. Google image search external antenna mod for literally hundreds of examples of that. Good luck @silvebemr \$\endgroup\$

    \$\begingroup\$ It is not a u.fl connector, it is some sort of switched test connector, hard to say exactly which one. \$\endgroup\$ Aug 7, 2015 at 21:40
