Recent Progress of Rectangular-Coordinate Orthogonal Multiplexing Antenna System for Non-Far Region Communication

This paper presents the recent progress of rectangular-coordinate orthogonal multiplexing (ROM) antenna system for non-far region communication using 16x16slot array antennas in the 60GHz band on two topics. One is the transmission enhancement by optimizing theexcitation coefficients for a given distance in the non-far region in order to increase the channel capacity. The other is the dual polarization use to double the channel capacity.
