Design and Investigation of Line-Defected Photonic Crystal Antenna for Outstanding Data Transmission

Abstract

Wireless technology now employs 5G (generation) communication, while 6G is the subject of increased research. Various G's have evolved due to the need to achieve high data transfer for reliable communication. A tremendous data transfer rate expressed in terabits per second (Tbps) is facilitated by the terahertz (THz) spectrum. The photonic crystal (PhC) patch antenna has been proposed in this chapter, and the consequences of a line defect were examined. The defect has been embedded in the perpendicular and parallel directions of the antenna substrates. The antenna's performance regarding return loss (RL), directivity, and voltage standing wave ratio (VSWR) is evaluated. The structure is simulated using CST, and the PhC structure results show excellent characteristics such as -48.02 dB RL, 1.007 VSWR, and 5.23 dB directivity at THz frequency.
