220GHz High Gain On-chip Antenna Based on 180nm CMOS

This paper presents an on-chip integrated antenna based on 180nm-CMOS process. By loading the artificial magnetic conductor(AMC) structure under the antenna, the antenna gain is improved and the radiation pattern is optimized. The peak gain of this antenna reaches 9.6 dBi with low side lobes. The bandwidth is increased to 212-227GHz by using a special structural connection between the feed line and the antenna.
