Broadband Equivalent Circuit Modeling of Self-Complementary Bow-Tie Antennas Monolithically Integrated with Semiconductors for Terahertz Applications

Abstract

We identify a broadband equivalent circuit of an on-chip self-complementary antenna integrated with a µm-sized semiconductor mesa structure whose circuit elements can be interpreted by using closed-form analysis. Prior to the equivalent circuit analysis, an electromagnetic simulation is done to investigate frequency independency of the input impedance for the integrated self-complementary antenna in terahertz range.
