摘要
本文基于空腔模型给出圆极化微带天线的一种简明理论,导出了对矩形单元的设计公式并作了实验验证。已证明,该理论对厚至0.084λ(?)(介质中波长)的基片仍是适用的。同时得出了圆极化带宽与基片厚度的关系式。已表明,若基片厚度约为λ_(?)的8％,可获得3％的圆极化带宽。
Based on the cavity model, a simple theory for circularly polarized microstrip antennas anddesign formulas for the rectangular patches are presented with experimental verification. It is shown thatthis theory is still applicable for substrate as thick as 0.084A. (dielectric wavelength). The relationshipbetween the Cp bandwidth (CP3W) and the thickness of substrate is given. It is shown that a CPBW of 3%can be obtained if the substrate is about 8% of λs thick,
