High Gain Terahertz Antenna on Flexible Substrate

Abstract

In this work, a high gain compact planar antenna array is proposed for Terahertz (THz) application. Proposed architecture is designed on Liquid Crystal Polymer (LCP), a flexible type substrate to make the structure conformal in shape. Parasitic coupling topology has been adopted to achieve high-gain of around 19.2 dBi on the planar configuration for 100 GHz application, suitable for several medical imaging purposes. The proposed antenna is fabricated using standard PCB industry and would be experimentally investigated for impedance and radiation pattern measurements thereafter. The work concludes with the electrical modeling of the antenna array structure.
