摘要

提出了一种利用ATF-34143场效应晶体管(FET)在最小噪声系数条件下设计的GPS应用有源集成天线(AIA)前端电路。对共同设计的探头馈电圆极化矩形微带天线(CPRMA)的射频和直流偏置电路进行了计算。为了优化性能，增加了一个源电感，并使用从实验反馈到联合电路/全波模拟结果的过程进行调谐，实现了高达13GHz的稳定性。实现并测试了原型;按照文中所示的详细步骤进行了NF和增益测量。

Directly matched active integrated antenna for GPS receiver

The design of an active integrated antenna (AIA) front-end circuit using the ATF-34143 field effect transistor (FET) in a minimum noise figure (NF) condition for GPS application is presented. Both RF and DC bias circuits are calculated for a co-designed probe fed circularly polarized rectangular microstrip antenna (CPRMA). To optimize performance a source inductance was added and tuned using a procedure that involves feedback from experimental to joint circuit/full-wave simulated results, achieving stability up to 13GHz. A prototype was implemented and tested; NF and gain measurements were performed following a detailed step-by-step process shown in this paper.
