Abstract:

 In this paper, arraymicro strip patch antenna with frequency reconfiguration is designed which produce different radiation pattern without changing the antenna dimensions and used to achieve a greater efficiency. Frequency reconfiguration is achieved by electrical reconfiguration technique which uses the varactor diode that was placed in the via hole to switch between various frequencies,because, varactor diode acts as a tunable device in RF circuits. The operating frequency of the antenna is 2.5 GHZ. So, the antenna size is reduced and achieved the gain of 4.8 db. The 3x1 array size represents the antenna elements and the feed point. Simulation is done by using the HFSS software (High Frequency Simulation Software). Because of compact size it can be used in receiver station of the IRNSS(Indian Regional Navigational Satellite) satellite system.

Keywords:
