An innovative design of a corner‐truncated inverted‐L patch antenna for achieving circular polarization (CP) operation over a wide bandwidth is presented. The antenna has a thick air‐layer substrate; however, it can be easily excited using a probe feed with a short probe pin. CP operation is obtained by selecting an optimal size of the truncated corners, and good impedance matching over a wide bandwidth is obtained by using a beveling technique on the vertical portion of the inverted‐L patch. For a prototype constructed for wireless local area network (WLAN) operation in the 2.4‐GHz band (2.4–2.484 GHz), the obtained CP bandwidth (3‐dB axial ratio) reaches about 7%, and the measured antenna gain is about 8.0 dBi across the CP bandwidth. Details of the antenna design and the experimental results are presented.
