Design of Modified SIW H-Plane Horn Antenna for Ku-Band Applications

In today's era of communication, Substrate Integrated Waveguide (SIW) is major part of development in Microwave and millimeter wave frequency range applications. In this paper, a novel design of H-plane SIW horn antenna is proposed for Ku-Band applications such as landing systems of an Aircraft radar, fixed satellite broadcast services etc., The proposed design of antenna is focused on producing improved bandwidth with variations in the tapered sections of the horn with respect to the conventional H-plane SIW horn antenna design. The design is simulated using the Keysight EMPro© 3D EM Simulation Software using FEM computational technique. Simulation results are analyzed, plotted and tabulated for various antenna parameters and are comparatively studied for conventional and modified structure respectively.
