Corrugated Substrate Integrated Waveguide Horn Antenna in C Band

Abstract
In this paper we proposed Corrugated Substrate Integrated Waveguide Horn Antenna in C band. CSIW is a new technology which is used to convert non planner devices in to planner form. In CSIW upper and bottom conducting plane are completely isolated by substrate, here the material is used for substrate with dielectric constant of 3.6.CSIW horn antenna designed and fabricated. Simulation is done in HFSS. Losses like radiation leakage, dielectric loss and dispersion are taken care while designing. The simulation results are verified with measurement. The objective of this paper is to provide broad perspective of CSIW horn antenna. CSIW horn antenna provides wide bandwidth. Keywords- CSIW, Dielectric Loss , Horn Antenna.
