Performance analysis of AMC-based bowtie-shaped slotted antenna for terahertz (THz) applications

Abstract

This paper presents the design and performance analysis ofAMC(artificial magnetic conductor)-based bowtie-shaped slotted antenna at a solution frequency 1.56 THz for a frequency range of 1.1–1.8 THz. In fact, a metamaterial-inspired structure, which acts as an artificial magnetic conductor (AMC), is used along with ground plane to enhance overall performance of the design. The characteristic parameters like return loss, VSWR, gain, and radiation pattern of proposed design have been presented and analyzed to exhibit the performance of the design proposed. The simulated results demonstrate that the designed antenna exhibits multiband in nature. The maximum gain of 6.14 dB and return loss of −20.14 dB are achieved at 1.56 and 1.4940 THz, respectively. HFSS simulation software is used for simulating the design.
