FABRICATION TOLERANCE AND GAIN IMPROVEMENTS OF MICROSTRIP PATCH ANTENNA AT TERAHERTZ FREQUENCIES

摘要

In this paper, a technique has been proposed to design microstrip antenna arrays at terahertz (THz) frequencies with improved gain and fabrication tolerance. The antenna is designed at 100GHz frequency and fabricated with simple laboratory based PCB etching process. The gain is improved to 13.4dBi with the help of only three patch elements. The measured -10dB return loss bandwidth (BW) is 5.55% of the central frequency. The measured and the simulation results are all in good agreement. (C) 2016 Wiley Periodicals, Inc.
