Design of Elliptical Patch Antenna with Partial Ground at THz Frequency Band

The evolution of wireless communication systems recently demanded a higher data transfer rate with enhanced bandwidth. The antenna design at the THz band is crucial in obtaining high bandwidth for increased data rate. The microstrip patch antenna is preferred as one of the most significant antennas for THz band applications. This paper proposed an elliptical patch antenna with partial ground methods to meet the speed demand of wireless communication systems. In this paper, Computer Simulation Technology (CST) is used to investigate the performance of the proposed antenna. The size of the antenna has been kept as 160×120 µm

. The simulation results indicate a large bandwidth of 1.18 THz and a low return loss of -33.07 dB with our proposed antenna. Moreover, the proposed antenna shows satisfactory enhancement in efficiency and gain. Based on the concept of the partial ground method, we investigate the performance of the proposed antenna through simulation results.
