Broadband Antenna Design for Terahertz Communication Systems

Abstract

This paper provides an overview of broadband terahertz antenna elements and arrays for integrated communication systems. The fundamental challenges of integrated on-chip and off-chip antenna design, the trade-offs between performance metrics, and the impact of interface between the chip and off-chip antennas are studied in detail. The limitations and benefits of various interface technologies are discussed. The deployment of printed circuit boards (PCB) and flexible printed circuits (FPC) technologies for implementation of efficient broadband antennas is compared against on-chip counterparts. As a proof of concept, an off-chip antenna for the 91–134 GHz is presented.
