✦ Synopsis

A high-gain dual-band antenna for the wireless local area network system is presented in this article. Two symmetrical linear arrays can be dynamically reconfigured that could switch radiation pattern with a switchable feed circuit between direction and omnidirection. The antenna can also be used for a pattern diversity antenna for the multiple-input-multiple-output communication systems. The design process for the antenna system is given, and the parameters and characteristics of the antennas are achieved by the method. Measured return losses, isolation, and radiation patterns are in good agreement with the simulated ones, which illustrates that the method is valid and the antenna system can be integrated with pattern reconfigurable and pattern diversity applications.

## Abstract In this paper, we present a compact dual‐band dual‐polarized aperture‐coupled patch antenna for 1800/5800 MHz DCS/WLAN applications. With properly designed feeding network and patch dimensions, the antenna can provide a pair of orthogonal linear polarization states for dual bands operat
