TeraHertz textile microstrip patch antenna design employing denim substrate for detection of TNT explosives

Abstract

In this paper, a textile terahertz reduced ground microstrip patch antenna for detection of trinitrotoluene (TNT) has been proposed. The proposed antenna is employing black denim as substrate having dielectric constant of εr = 1.6. The design and simulation of antenna has been carried out using CS T Microwave Studio 2014. The ground and patch of the proposed antenna has been designed using copper of thickness 0.05μm. It has been analyzed that the proposed antenna has impedance bandwidth of 247 GHz with an operating frequency range of 8.0481THz-8.3321THz with resonant frequency of 8.208 THz. It has been observed that the textile terahertz reduced ground microstrip patch antenna has gain of 7.359 dB and directivity of 7.002 dBi. The proposed antenna has minimal return loss of −65.89 dB at resonant frequency of 8.208 THz. The proposed antenna can be suitably employed for the detection of the TNT explosives and drugs.
