Abstract
Owing to the revolutionary development in the field of terahertz technology numerous advancement has taken place. In order to make a contribution to this field the proposed work focuses on the design and analysis of terahertz microstrip patch antenna that can be suitably deployed for determination of vitamins L-ascorbic acid and Thiamine hydrochloride. Flame Retardant (Fr4) material with thickness of 1.6 ?m has been deployed as dielectric substrate with electrical permittivity of 4.4. The patch and ground plane are made up of copper of thickness 17 microns. A rectangular slot has been introduced in middle of the ground plane in order to improve the return loss of the antenna. The design and simulation of proposed antenna has been done using Computer Simulation Technology (CST) Microwave Studio 2016. Analysis of the proposed antenna has been done on various antenna parameters like return loss (S11), directivity(dBi), gain (dB), Half Power Beamwidth (HPBW) and impedance. It has been observed that the designed antenna is resonant at 3.12 THz with an impedance of 50.77 ?. The designed antenna has return loss (S11) of -36.40 dB at resonant frequency of 3.12 THz with a gain of 4.56 dB and directivity of 5.69 dBi which makes it suitable for detection of vitamins L-ascorbic acid and Thiamine hydrochloride.
