Design and Simulation for 5G Millimeter-wave Plane Wave Generator

Abstract

Plane wave generator (PWG) is a phased array system that can create a plane wave in the quiet zone (QZ). By setting a number of appropriate complex weights on PWG elements, wireless devices can be measured at a shorter distance. However, for the 5G millimeter-wave frequency range, the PWG system confronts many new challenges due to high operating frequency and huge bandwidth. In this paper, the plane wave synthesis is discussed from the point view of sparse representation, and a novel orthogonal match pursuit algorithm has been proposed for PWG design. Moreover, plenty of simulation works have been performed in this paper. The simulation results show that the proposed algorithm can synthesize the QZ over a wide frequency range with limited excited PWG sources.
