Abstract

A new broadband singleโ€fed circularly polarized (CP) wideโ€slot antenna is presented in the letter. The antenna is composed of a wideโ€slot, with a Tโ€shaped stub and a microstrip Tโ€junction. The CP operation is realized by the interaction from the Tโ€shaped stub on the wideโ€slot and the Tโ€junction. The antenna has been investigated numerically and experimentally. Measured result shows that the antenna has an impedance bandwidth of 58% and a 3โ€dB bandwidth of axial ratio of 22.2%. ยฉ 2007 Wiley Periodicals, Inc.
