一种新型的双频带可植入天线设计

设计了一款工作在医疗设备通信服务频段（MICS，402~405 MHz）和工业、科学和医疗频段（ISM，2.4~2.48 GHz）的新型小型化双带植入天线。通过合并一个螺旋辐射带和一个U型辐射带，天线能形成紧凑的双平面倒F （PIFA）结构。包括上下基片层的天线总体积为17 mm×16 mm×1.27 mm。测量的低频带和高频带的–10 dB带宽分别为412~436 MHz和2.4~2.5 GHz。此外，研究了天线的辐射特性及比吸收率（SAR）。

RECONFIGURABLE DUAL-BAND CIRCULARLY POLARIZED MICROSTRIP PATCH ANTENNA FOR WIRELESS APPLICATIONS

A new design of reconfigurable single-feed circular patch microstrip antenna for dual-band circular polarization application is proposed. The dual-band functionality is realized through incorporating cross-slots of equal slot length in the circular patch and utilizing two PIN diodes to switch the slots on or off. A pairs of tuning stubs are used to tune the circular polarization performance. The design process is presented and good results were obtained.
