A convenient circuit model for millimeter-wave substrate integrated waveguide (SIW) corporate feed for dielectric resonator antenna arrays

In this paper, a generic simple circuit model for 1 x M SlW-parallelfed DRA linear array is presented as a fast method for the analysis and optimization of the larger arrays. This circuit model provides good estimates for the antenna return loss and radiation pattern characteristics. It is based on N-port circuit analysis of the antenna system.
