Abstract

This paper presents a new equivalent circuit model for Artificial Magnetic Conductors (AMCs), proposes a new AMC unit cell that provides a large capacitance, and set guidelines to design efficient antennas in CMOS technology characterized by lossy silicon substrate that has thickness slightly smaller than λ/4 of the radiation frequency. The proposed procedure is investigated in the design of a dipole antenna that operates at 60 GHz in 65 nm CMOS technology. Theoretical results are confirmed by two different commercial simulators. The antenna is matched within the entire band of operation (i.e. 57 GHz to 64 GHz) with peak simulated gain and total efficiency of +2 dBi and 52%, respectively. The size occupied by the antenna and AMC structure is 1.2 mm ×1.8 mm.
