Abstract

AbstractA patch antenna with an inverted‐V ground plane capable of achieving a wide horizontal radiation pattern for a WLAN access point in the 2.4‐GHz band is presented. The inverted‐V ground plane comprises a narrow central ground portion for setting the 50Ω SMA connector for the patch antenna and two bent ground portions to control the broadening of the antenna's horizontal radiation pattern. By selecting the proper dimensions, the proposed antenna can have a wide horizontal radiation pattern of about 170° (3‐dB beamwidth) with vertical polarization, which is very suitable for WLAN access‐point applications where uniform radiation in one direction or one half‐space is required. © 2004 Wiley Periodicals, Inc.
