Intern GSM-antenn 3 dBi
That's one slim cellular antenna! At just 75mm long from tip to tip and with a thickness of just 2mm, this 3dBi GSM antenna is smart, compact and sensitive, with a 3dBi gain. The antenna juts out from its base with stick-on back, so you attach it to an enclosure if you're making something like, say, a DIY phone. It has a tiny uFL connector on the end - which is perfect for the FONA - but will also work well for any other RF project on the 850/900/1800/1900/2100 bands, such as any other Cellular or GSM / GPRS device.
