本論文開發具有圓極化且頻率響應可重組之頻率捷變型天線。天線採用可輻射圓極化電磁波之阿基米德螺旋(Archimedean spiral)結構，並串接以可變電容二極體(varactor)調控之可重組式巴倫帶通濾波器，實現可接收GPS L1頻段與L2頻段等不同全球衛星定位訊號之頻率捷變天線，實作天線以反射損耗10dB為標準，可調操作中心頻率介於1250MHz至1550MHz，可調頻寬介於50 MHz至100 MHz，最高增益約3dB且具有軸比3dB以下的圓極化特性，並經由實地接收衛星訊號進行定位驗證。

This thesis aims for the development of frequency-agile circularly-polarized antenna. The Archimedean spiral is adopted for realization of a structure for radiating circularly polarized waves, and the varactor-based reconfigurable balun bandpass is integrated for attaining the tunable operations at different GPS regimes around the world, including GPS L1 Band and L2 Band. The antenna design is experimentally verified, and the measured results show that the antenna has tunable center frequencies ranging from 1250 to 1550 MHz along with a tunable bandwidth of 50 to 100 MHz. Also, the antenna is integrated with commercial GPS receiver modules to demonstrate its effectiveness on GPS signal reception.
