DESIGN AND SIMULATION OF HORN ANTENNA AT 2GHZ WITH HFSS

Abstract: The design and simulation of a rectangular pyramidal horn antenna at 2GHz are described in this work, which may be utilized in electromagnetic sensing, antenna calibration, microwave heating and different wireless communication systems. Pyramidal horn antennas have many merits such as simple in manufacturing low fabrication cost, moderate bandwidth; because of these merits, they find more applications in electromagnetic compatibility measurements and radars. To design the desired horn antenna a maximum gain of 15 dB at 2 GHz is considered and the range of frequency chosen is 1.6 to 2.4GHz, which is often L-band or S-band. The horn antenna design and its simulation are explained in this study. ANSYS HFSS software was used for the simulation. A gain of 12.94 dB was attained at 1.96 GHz, according to the simulation results.
