A SIMPLE EM DIPOLE RADIATING ELEMENT FOR DUAL-POLARIZED PHASED ARRAY WEATHER RADARS

Abstract

The Dual Polarized radiating element is a critical component in the Multi-function Phased Array Radar (MPAR) System. This thesis studies a new type of dual polarized radiating element based on the Electro-Magnetic (EM) dipole concept. Two different geometries i.e., loop approximated as magnetic dipole and a printed electric dipole are used to form a single dual polarized radiating element. Radiation patterns based on Ansoft® High Frequency Structural Simulator (HFSS) simulation software and measurements carried out in Anechoic Chambers are presented. The results are compared to commercially available electric and magnetic dipole antennas. An Initial array and simple linear array design based on these elements is also discussed.
