TRIPLE BAND THZ MIMO ANTENNA FOR SHORT-RANGE COMMUNICATIONS

Abstract

For wireless applications, a single-patch antenna having a shape slot is suggested along with a 1×8 Multiple Input Multiple Output (MIMO) antenna array. The substrate is made of polyimide material, which has a 0.04 mm thickness and a dielectric constant of 3.5. The proposed MIMO antenna array uses a remarkably small rectangular microstrip patch antenna with dimensions of 0.075mm by 0.111mm by 0.04mm. Performance measures such as return loss, bandwidth, antenna gain, antenna efficiency, and VSWR ECC are computed for resonating frequency. The designed MIMO antenna array resonates for three different frequencies of 0.7487 THz, 0.8015 THz, and 1.1558THz and has a return loss of less than -10 dB. The designed array has an antenna efficiency of 96% and a maximum achievable antenna gain of 16.5 dB for resonating frequency. Due to its improved properties, the designed antenna array might be suitable for a range of THz applications.
