A Wideband Dual Polarised Hat Feed-based Ku-Band Reflector Antenna for Man Portable Satcom Application

Abstract

This paper describes the design, simulation, and development of an accustomed 0.76-meter hat feed-based Ku-band reflector antenna for a man-portable Satcom application. The antenna uses a small f/D ratio of 0.25 for reducing spillover radiation & low far-out sidelobes besides making the antenna compact. This lightweight antenna with a manual pointing system (elevation over azimuth) can operate simultaneously over the complete transmit and receive frequency band of Ku-band Satcom. The designed antenna was simulated in High Frequency Structure Simulator (HFSS) software and results were verified in GRASP (TICRA) software. The measured VSWR of the antenna is 2:1 over the complete receive and transmit frequency band..........
