摘要：

This paper introduces a new way of building a cross-slot coupling patch antenna to generate duel polarization with a CPW feed line on single layer for the EHF band around a center frequency of 38 GHz. The antenna structure developed combines the advantages of CPW (Coplanar Waveguide) with the advantages of aperture-coupled microstrip antenna, and simplifies the structure of the antenna by reducing the number of metallization level from 3 dawn to 2, thereby making easier the integration of the active devices. In addition. this type of coupling is advantageous when applied to millimeter wave monolithic phased arrays. A unique feed design eliminates the competition for surface space between the antenna elements and the feed network. In addition, the ground plane shields the antenna half-space from spurious radiation emitted by feed lines and active devices. The antenna is designed on a high dielectric constant substrate (epsilon r = 9.9), which is close to the dielectric constant of GaAs and demonstrates the feasibility of integration of such an antenna structure into monolithic circuits.
