Dual-band operation vertical patch antenna for WLAN applications

Abstract

In this paper, a novel design of the dual-band operation vertical patch antenna are proposed. The structure of proposed antenna consists of two vertical patches which is different from the architecture of traditional planar antennas. By utilizing the broadband feeding mechanism, the antenna bandwidth is significantly increased. And, two separate wide resonant modes for WLAN applications can be generated by introducing the shorted parasitic patch into the structure. An optimal design for wideband operation will be presented and discussed.
