Hybrid beam steerable phased array antenna for satcom OTM with 16 GHZ feed signal

Abstract

Now a day there is a great demand for communication On the Move (OTM). OTM antenna is system which is mounted on a vehicle such as boat, train, car, flight, and this system is used to track the satellite link and maintain the link between the terminal and satellite even when the vehicle is moving. The antenna always steer to track the satellite link while motion. Phased array antenna with hybrid beam steering method is proposed in this paper to achieve effective communication. The beam Formed in phased array of 100 isotropic elements has a wide beam width. But, to fetch satellite communication applications, the beam width a narrow beam width is required. Hence a parabolic reflector is chosen to sharpen the beam. But, for the ease of simulation, in place of the array of antennas, a horn antenna design to operate at the same operating frequency, 16 GHz is given as a feed to the reflector antenna and the simulation is done using HFSS.
