Abstract

A printed antenna with frequency and pattern reconfiguration is presented in this letter to meet the requirements of IEEE 802.11a/b/g/n and 802.16 standards. By controlling five p-i-n diodes, the antenna can be considered as a planar monopole or a microstrip patch and has three operation modes, i.e. an omnidirectional pattern mode at the lower frequency band of 2.21-2.79 GHz, a unidirectional pattern mode at the higher frequency band of 5.27-5.56 GHz, and both of them working simultaneously. It provides a low-profile, low-cost, and reconfigurable solution for multistandard wireless communication applications.
