A linear-scaling technique for designing a THz antenna from a GHz microstrip antenna or slot antenna

Abstract

With the increasing need for higher and higher bandwidth, wireless communication standards are moving towards higher frequencies. The fifth generation (5 G) wireless communication standards are already set to millimeter waves and the research trends are advancing towards exploring the terahertz (THz) frequencies. Most of the design methodologies for microstrip antennas and other communication devices are developed in the GHz frequencies already. In this paper, a novel linear-scaling technique is presented for bridging the years of research in microstrip and slot antennas in GHz frequencies to the future generation of THz antennas. The technique is analytically justified for a rectangular patch antenna and experimentally validated for a wide band slot antenna and a metamaterial based antenna with integrated filters.
