DESIGN OF X BAND PYRAMIDAL HORN ANTENNA

A horn may be considered as a flared out waveguide. In this paper, a powerful electromagnetic simulator, 3D EM solver WIPL-D software is used to design, analyse and optimize the dimensions of horn antenna which is based on MOM solution for computations. The standard horn antenna at 10 GHz for 15dB gain is modelled and the radiation pattern was observed. The horn antenna is optimized to achieve more than 20dB gain using Genetic Algorithm, radiation patterns of the optimized horn antenna are also presented. Geometry of the horn can be modelled by exploring the toolbar ‘symmetry’ option in WIPL-D. Design of X band Pyramidal Horn Antenna is fabricated and measured using Network Analyzer.
