Abstract

A field coupled detector is presented including planar antenna design as well as the video amplifier topology. The compact antenna design is suitable for application in dense antenna arrays. Particularly an array concept is shown that suits for holographic imaging at frequencies beyond 200 GHz. For this purpose a broadband planar antenna is designed for frequencies from 230 GHz to 325 GHz, allowing for high depth resolution in an imaging system. Optimization methods utilized to improve the antenna perfomance are discussed. The presented transimpedance amplifier design offers a low noise figure and a protection for the diode, as it regulates the diode voltage to zero. An optimal diode impedance for this amplifier topology is derived. Simulation and measurement results are presented. © 2013 European Microwave Association.
