" iPhone 3G delivers UMTS, HSDPA, GSM, Wi-Fi, EDGE, GPS, and Bluetooth 2.0 + EDR in one compact device — using only two antennas. Clever iPhone engineering integrates those antennas into a few unexpected places: the metal ring around the camera, the audio jack, the metal screen bezel, and the iPhone circuitry itself."
Does anyone knows what kind of antennas that 3G iphone used ? Only two antennas for so many applications !

我也很想知道,恳请高人指点
以FPC製作
Cable共焊的方式構成兩組吧
好像现在手机天线很多都是FPC做的吧..
阿里巴巴上找的...看来只有两个天线...个人觉得这天线应该没有覆盖GSM低频部分

谢谢小编,见识一下。
柔性PCB天线调试方便。
谢谢分享,低频肯定是要的,不然到了中国只用1800吗,可以用电感把它拉到低频去
只是觉得靠那么近,隔离度还能做好,确实很有实力
3GIPHONE的网络频率是UMTS/HSDPA (850, 1900, 2100 MHz);GSM/EDGE (850, 900, 1800, 1900 MHz);
与第一代最大的区别就是加了WCDMA
