Dual frequency microstrip hexagonal patch linear array antenna integrated with RF-MEMS switches

Abstract

Dual frequency band microstrip hexagonal patch linear array antenna integrated with RF-MEMS switches is proposed which can operate at dual frequencies on the basis of reconfiguration of the geometrical structure. To reconfigure the structure an additional hexagonal patch ring is placed around the main patch with MEMS switches. These switches are incorporated to hexagonal patch to control or change the frequency. The linear array of these hexagonal patches gives more directivity and scanning power, which makes it useful in many communication systems.
