Design & implementation of a standard gain horn antenna for optimized gain and radiation pattern using MathCAD & HFSS

This paper is about the design and implementation of a standard gain horn antenna using MathCAD & High frequency structure simulator (HFSS) Software. The horn was designed by implementing a procedure in MathCAD. Simulation & optimization of the horn was carried out in HFSS based on finite element method (FEM). The reason to simulate the horn in HFSS is the fact to achieve optimum gain and equal radiation patterns in both E-plane & H-plane (pencil beam). Itpsilas also easy in HFSS to optimize the various dimensions of the horn for optimum results. After the simulation & optimization, the horn was manufactured and tested. The results of the finalized simulation and actually manufactured horn are very close to each other.
