Q Slot Terahertz (THz) Novel Antenna Design for Wireless Communication

This paper presents a Q slot novel Terahertz (THz) antenna design for wireless communications. The proposed antenna is a rectangular antenna made out of rectangular radiator and elliptical slot that fed by coaxial transmission line. The antenna works at dual bandwidth frequency groups in terahertz frequency spectrum. Over the century there was a huge development established in wireless technology but we are still searching for more improvement on this field. Wireless networking is one of the major research fields in the field of wireless technology. Today, communication systems and an analysis of communication systems are being carried out unfinished without an awareness of the process and produce of for antennas. This was the key reason for our work based on such a sector. People started to use infrared for over a century. Now a day's people have begun to use mm-wave in communication systems. But there is a frequency band between mm-waves and the infrared region called sub-mm-wave or terahertz in the electromagnetic spectrum that still unused in practical technology, producing and detecting radiation. It is classified as wavelengths of 3 mm to 10 μm from 0.3 to 30 THz. Useful power generation and receiver technologies are currently under development at frequencies within this range. The area of antenna research is extremely vast. The design and simulation of patch antennas is therefore our main focus. So we focus on optimization of a patch antenna feed by a 1 THz to 3 THz which got a rectangular probe and a Q-slot on it. We evaluate the configuration of the proposed antenna and determine its output in terms of return loss, bandwidth, gain, efficiency, and radiation patterns. The antenna is design and simulated by CST studio. Further testing and simulation is under development.
