摘要： 设计了一种适用于超薄手机的四频带PIFA天线，采用插销和寄生负载技术实现天线的多频带.将馈电位置下面地板开槽和馈地探针直接接入大地板增强天线辐射.此外，利用π形无源匹配技术减小天线的回波损耗，进一步增强天线的辐射效率.实验测量表明，该天线能工作在GSM900/DCS/PCS/UMTS 4个频段，且辐射效率分别为38％、40％、42％和39％.

Abstract: It presents the design of a lowprofile quadband PIFA antenna for mobile phones. The Antenna has multiband characteristics via the use of two slot and parasitic load. To enhance antenna radiation, three technologies were applied, such as digging out the ground under the feed, joining directly up groundfeed and the ground, and using passive π matching network. Experimental results show that the antenna has very good radiation performance in GSM900/DCS/PCS/UMTS operating bands, the efficiency of which is 38％、40％、42％ and 39％ respectively.

Key words: lowprofile; multiband antenna; PIFA; mobile Phone
