Abstract

This letter demonstrates a new design of a probe‐fed patch antenna with a modified antenna ground, and a constructed prototype ideal for applications in a 2.4‐GHz WLAN access point is presented. The antenna has a thick air substrate for broadband operation and is fed by an inclined probe pin at the edge of the patch bent portion. The antenna ground comprises different portions and is in the shape of a step. With the proposed probe feed and ground configuration, good impedance bandwidth with VSWR below 1.5 over the 2.4 GHz WLAN band can be obtained. In addition, good broadside radiation characteristics have also been observed. © 2008 Wiley Periodicals, Inc.
