In this paper, design and analysis of a new type of Substrate Integrated Waveguide (SIW) antenna and a pair of inverted complimentary U-shaped slots are proposed with considerable effect of a single reflection cancelling via (RCV) at the center of the structure. The position of the complementary slots with respect to the RCV is varied for getting the resonant frequency within microwave x-bands (≈11 GHz) and the effect of these variations are presented in the form of parametric graphs. Elementary array of vias are used to enhance the return loss as well as the gain of the antenna. The proposed antenna is designed over FR4 substrate material of dielectric constant 4.4 and with a thickness of 1.6 mm using Ansoft HFSS Microwave CAD tool.
