所有智能手机都有“信号门”
http://www.apple.com/antenna/Every smartphone has a cellular antenna. And nearly every smartphone can lose signal strength if you hold it in a certain way. To demonstrate this, we tested iPhone 4 alongside other smartphones. 所有手机遮住天线都有信号门，但是iPhone 4的天线X点实在是太容易握到 麻痹通信行业全部泪流满面。 apple这次准备作死, 准备看整行业PR全开么 RIM已经反击了
Apple\'s attempt to draw RIM into Apple\'s self-made debacle is unacceptable 其实设计一个850/900/1800/1900/2400的天线没啥难度, 但是Droid X如果塞了两个, 就比较新鲜了
其他企业再脑残, 也不会把天线裸露外面 幫主爲了解脫果然無所不用... 二楼竟然认为M8不是智能机，身为煤油俺不答应。 “只不过没穿小裤裤，你们怎么这么大惊小怪啊！” 本帖最后由 Stank 于 2010-7-17 17:36 编辑

Rx Diversity，高通早就有芯片方案了。不过受制于体积，很少有厂商愿意用。上网卡倒是常用。 我的n95 8g不管怎么握也没遇到过信号下降 本帖最后由 Castiel 于 2010-7-17 18:56 编辑

Rx diversity做得差还不如单天线呢...手上这个nokia dongle, 双天线, 悲剧得一塌糊涂... 我用过的手机说明书上都写着天线大概在什么位置，请不要遮挡或用手捂住。但苹果为什么要放在左下…………而且竟然还能通过测试！ 别被蒙蔽了, 苹果的问题和天线遮盖没啥关系 移动广告告诉我们，水果要送保护套了…还在嘴硬阿 苹果这调调太恶心了。
RIM回喷的好给力。
“Apple’s attempt to draw RIM into Apple’s self-made debacle is unacceptable. Apple’s claims about RIM products appear to be deliberate attempts to distort the public’s understanding of an antenna design issue and to deflect attention from Apple’s difficult situation. RIM is a global leader in antenna design and has been successfully designing industry-leading wireless data products with efficient and effective radio performance for over 20 years. During that time, RIM has avoided designs like the one Apple used in the iPhone 4 and instead has used innovative designs which reduce the risk for dropped calls, especially in areas of lower coverage. One thing is for certain, RIM’s customers don’t need to use a case for their BlackBerry smartphone to maintain proper connectivity. Apple clearly made certain design decisions and it should take responsibility for these decisions rather than trying to draw RIM and others into a situation that relates specifically to Apple.”

现在为啥手机天线都不做成以前有个小棒棒突出的那种了？ 现在为啥手机天线都不做成以前有个小棒棒突出的那种了？

看诺基亚的反击文就知道了, 98年第一台内置天线手机 其实没有人会期望才出了4台手机的企业能把手机部分做得有多好。。。
不过这样拉其他人下水也那个了点。。。 现在为啥手机天线都不做成以前有个小棒棒突出的那种了？

损失大概3dB的增益，能在外观体积便携等方面获得很大提高 苹果本身就是娱乐手机
