摘要：
A new broadband single-fed circularly polarized (CP) wide-slot antenna is presented in the letter. The antenna is composed of a wide-slot, with a T-shaped stub and a microstrip T-junction. The CP operation is realized by the interaction front the T-shaped stub on the wide-slot and the T-junction. The antenna has been investigated numerically and experimentally. Measured result shows that the antenna has an impedance bandwidth of 58% and a 3-dB bandwidth of axial ratio of 22.2%. (c) 2007 Wiley Periodicals, Inc.
