Frequency reconfigurable microstrip circular patch array antenna integrated with RF-MEMS switches

A microstrip reconfigurable array antenna with integrated RF-MEMS switches is proposed which can operate at dual frequencies. The switches are incorporated to circular patch to control or change the frequency. The array of these circular patches gives more directivity and scanning power, which makes it useful in many communication systems.
