Microstrip Patch Antenna, Multi Band and Frequency Tunable Antennas, Coaxial Feed


A coaxial fed frequency tunable slot loaded RMSA that resonates at multi band is presented in this paper. The rectangular patch of LXW is placed on a FR4 substrate at a height of 72mils above a ground plane. Multi band is achieved by placing slots. Coplanar arrangement of second patch at some gap is used for frequency tuning. Designed antenna resonates at multi band (10.6GHz & 20.6GHz) which can be used for the X-Band (Radar, Satellite Communication, and Wireless Computer Networks) and K-Band (Long Distance Communication). Tuning of these frequencies is also presented. Designed patch has a good impedance matching with an average gain of 9dB.
