Performance Analysis of Corrugated Horn Antenna for Liquid Level Measurement Application

Abstract

In this paper, we have proposed the design and performance analysis of corrugated horn antenna for non-contact liquid level measurement applications. The performance of corrugated horn antenna is dependent on corrugation profile, depth and period of corrugations. It gives higher gain, wide bandwidth, low side lobe level and better isolation from cross-polarization component. One of the best merits of the profiled corrugated horn antenna compared to rectangular or circular horn antenna is in compact size. The proposed design is simulated using computer simulation technology (CST)-microwave studio software based on finite integration technique. The simulation results show that it gives very narrow beam width and better isolation value in operating band.
