A 60-GHz on-chip antenna over an AMC using a standard 65-nm CMOS technology

This paper presents a design process and simulation results of a U-shaped antenna over an artificial magnetic conductor (AMC) using a standard 65-nm CMOS technology for 60-GHz applications. The structure of the proposed on-chip antenna consists of a U-shaped monopole antenna fed with conductor-backed CPW line at the terminal aluminum layer LB and a novel AMC constructed with M1 to M6 metal layers. Ansoft HFSS is used for design simulation. Based on the simulated results after optimization, the U-shaped CPW-fed monopole antenna mounted on the AMC can offer higher gain and wider impedance bandwidth while maintaining an electrical size reduction.
