摘要：
Truncated-corner probe-fed (TCPF) patches are popular for their simple design that provides circularly polarized (CP) radiation with a very low axial ratio (AR). For a thin substrate (∼ 0.026λ), this antenna provides approximately 0.3% CP bandwidth (BW) (AR 3 dB along with S11 -10 dB). However, as the substrate thickness is increased for enhancing the matching BW, an offset among the frequencies featured with minimum AR and optimum S11 is observed. This degrades the effective BW, with an overlapping of both S11 <-10 dB and AR < 3 dB. © 1990-2011 IEEE.
