Abstract

New designs for compact reconfigurable antennas are introduced for mobile phones. Based on the new antenna designs a reconfigurable multiband operating antenna using in mobile phone is studied which can select two groups of operation frequency bands adaptively by electronically. In particular, each group of frequency bands can serve several different communication systems which may include various combinations of GSM850, GSM900, DCS, PCS, and UMTS simultaneously. Therefore, a various of communication systems can be conveniently served through only one antenna by electronically selecting different antenna modes. One strong point is that through the different working modes, the total antenna physical volume can be reused which make the overall antenna pattern more compact. In the first design mode it can support GSM900, DCS1800, PCS1900, and UMTS. In the second antenna mode, it can cover GSM850, DCS1800, PCS1900, and UMTS. The designs are investigated when ideal switches is applied. The designs are verified through both numerical simulations and measurement of an experimental prototype. The result confirms good performance of the multiband reconfigurable antenna designs.

手机可重构多波段天线设计

介绍了用于移动电话的紧凑型可重构天线的新设计。基于新的天线设计，研究了一种可重构的多频段工作天线，该天线可以通过电子方式自适应地选择两组工作频段。特别是，每一组频带可以服务于几个不同的通信系统，这些系统可以同时包括GSM850、GSM900、DCS、PCS和UMTS的各种组合。因此，通过电子方式选择不同的天线模式，可以方便地通过一个天线为各种通信系统服务。一个优点是通过不同的工作模式，可以重复利用天线的总物理体积，使整体天线方向图更加紧凑。在第一种设计模式下，可以支持GSM900、DCS1800、PCS1900和UMTS。在第二种天线模式下，可以覆盖GSM850、DCS1800、PCS1900和UMTS。对理想开关的设计进行了研究。通过数值模拟和实验样机的测量验证了设计的正确性。结果证实了多波段可重构天线设计的良好性能。
