A gain enhanced 60 GHz CMOS antenna-on-chip using off-chip Mu near zero metamaterial lens

This paper presents a Mu Near Zero Metamaterial (MNZ-MM) lens to enhance the gain of a 60 GHz Antenna-on-Chip (AoC). First, a MNZ-MM unit cell is designed to ensure the near zero characteristics at the 60 GHz band. Furthermore, a 3 by 3 matrix of the MNZ-MM is placed in the desired direction of radiation such that the radiated waves are coupled and the gain is enhanced and the AoC's |S11| is negligibly affected. The simulated gain and efficiency of the AoC with MNZ-MM lens are 2.8dBi and 35%, respectively.
