Electronically Reconfigurable High-Gain Steerable Antenna for Mobile Satellite Communication

An electronically reconfigurable parasitic printed antenna is proposed for beam steering in Mobile Satellite Communication. Parasitic antenna array with an RF switch successfully steer the beam in elevation plane as well as in azimuth plane. Control of the beam steering angle is achieved with the effect of parasitic array and RF switch. Two RF switches enable three modes of operation, in which the beam is able to steer in three directions with angle ?? °, ? °, ??? − ?? ° . The antenna resonates at 3.5 GHz with the high gain response. The geometry of the proposed antenna is implemented on an FR4 substrate with ?? × ?? × ?. ?? ??? of physical dimension. The observational study was carried out using IE3D EM Simulator.
