Design of 26GHz On-Chip Antenna for Microsensors Based on a Standard 0.18μm CMOS Process

Abstract

With the rapid development of 5G communication network, microsensors become more and more important because they could be the solution of Internet on Everything. To realize microsensors, the miniaturization of antenna is a key issue. The paper demonstrates a 26GHz on-chip antenna for microsensors based on standard 0.18μm CMOS process. Through the introduction of hexagon artificial magnetic conductor structure, the antenna gain is enhanced. The antenna has a peak gain of −7.2dBi and a good front-to-back ratio. The working frequency band of the antenna spans from 21.67GHz to 29.99GHz (32% of center frequency), rendering the antenna capable for 5G communication based on 26GHz frequency band.
