Terahertz Antenna for Medical, Astronomyand Defence Development

Terahertz (0.1-10 THz) wireless communication will be the next-generation technique for achieving high data rates. THz is one of the most attractive possibilities for 6 G systems since it provides large bandwidth, up to 100 GHz, and massive data throughput of up to 1 Tbps. Since the 6 G can achieve the highest high-speed data rate, highly dependable communication, huge connection, and extremely low latency connectivity, it seeks to further improve upon the qualities of the 5G. This paper represents the rectangular DRA of microstrip defective ground structure antennas (DGS). The suggested microstrip DGS antenna performs better than the traditional microstrip. The suggested antenna provides the band (6.58.4THz) The resonant frequency of the band is 7 THz S11 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$=-57.61 ~\text{dB}$</tex>. For the band, we obtained a bandwidth of 27.14 %. Qfactor for the band is 3.64 Maximum Gain 5.47 dB at 7 THz. Radiation efficiency is greater than 90.06 % within the targeted operating frequency band <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$6.5-8.4 \text{THz}$</tex>.VSWR of the resonant frequency of 7 THz is 1.01. The proposed antenna is used in high-speed communication, medical imaging, spectroscopy, quantum research, astronomy, and defense.
