Abstract

A low cost and high radiation efficiency planar two dimensional (2D) antenna array design based upon substrate integrated waveguide (SIW) hybrid feed technology is proposed. It is more convenient for highly efficient millimeter-wave (mm-Wave) applications such as radar sensing and wireless communication. The SIW is a low loss structure that minimizes conduction loss which dominates at mmW. A general 2D N×M planar antenna array architecture made of two dielectric substrate layers is presented. As an example, 2×4 SIW-DRA array module operating at 38 GHz is designed and simulated using HFSS full-wave solver. The simulated maximum broadside gain is 14.50 and high radiation efficiency of better than 80 % within an operating bandwidths of 1.57 GHz.
