Design, simulation, development & testing of wideband high performance pyramidal horn feed for terrestrial microwave (LOS) communication in mobile & wireless applications

This paper discusses the design, simulation, development & testing of wideband, medium gain, lightweight, wide beamwidth pyramidal horn feed for terrestrial microwave line of sight communication in mobile & wireless applications. This antenna feed has been designed for X-band frequencies widely used in terrestrial microwave communication for mobile & wireless applications. Simulated & Developed feed shows wideband characteristics of VSWR <; 2 for bandwidth range of minimum 2.5GHz. Antenna is linearly polarized and show wide beam characteristics in azimuth plane with an minimum gain of 12.5dB. E-field & H-field analysis for X-band pyramidal horn feed has also been conducted. Applications for pyramidal horn feeds have also been discussed. Absolute gain measurement techniques have been employed for the measurement of antenna gain. Design meets the ruggedness, strength & reliability, durability, weight, corrosion resistance, temperature variation requirements of terrestrial/ line of sight (LOS) communication. Design, Simulation & Optimization for X-band pyramidal horn antenna feed has been done on Ansoft HFSS v11.
