摘要

提出了一种用于全球定位系统和无线局域网的双频圆极化微带天线的设计方案。该天线提出了一种带短段馈线的倒l形天线，以实现双谐振频率并表征天线的极化特性。仿真和测量结果表明，该天线可以在1575.42 MHz和2450 MHz的频率下工作。在这些频率下，它具有右圆极化，其圆极化带宽分别为57.1 MHz和223.2 MHz。采用fr4 -环氧介电基板，测量GPS频率获得1.49 dBi增益，而在WLAN频率获得3.16 dBi增益。

Dual Band Circularly Polarized Microstrip Antenna Fed By Inverted-L Shaped With A Stub for GPS And WLAN Application

A design of dual-band circularly polarized microstrip antenna for Global Positioning System and WLAN application is presented. This antenna proposed an inverted-L shaped with a stub as a feedline to achieve dual resonant frequency and characterize polarization of the antenna. From the simulated and measurement result showed this antenna can operate at frequency 1575.42 MHz and 2450 MHz. At those frequencies, it has right-hand circular polarization where its circular polarization bandwidth is 57.1 MHz and 223.2 MHz respectively. Using FR4-Epoxy dielectric substrate, measured GPS frequency obtained 1.49 dBi of gain while at WLAN frequency has 3.16 dBi.
