9 RO ,VVXH Reconfigurable Multi- Band Antenna Using RF MEMS bandwidth(BW) [5], or by frequency- reconfigurable antenna (FRA) [6] with a narrow operating bandwidth that can be turned over the entire band. We can say that among the three approaches, the frequency - reconfigurable antenna approach provides an optimum solution. This can be achieved by using a single RF MEMS ohmic contact Reconfigurable Microstrip Patch Antenna using MEMS Technology higher resonant frequency. The antenna was designed and analyzed using ANSOFT HFSS. Keywords –Reconfigurable Antenna, Frequency Diversity, Patch Antenna, Switchable Slot I. INTRODUCTION In the field of wireless communications, a very important development is the integration of different A Frequency-Reconfigurable Circularly Polarized Patch Antenna ... A microstrip antenna with integrated RF mircoelectromechanical system (MEMS) switches is proposed and demonstrated to operate at dual frequencies with circular polarization. The switches are incorporated into the diagonally-fed square patch for controlling the operating frequency and a rectangular stub attached to the edge of the Reconfigurable Double Slot Ring Antenna for Bandwidth Enhancement
