Abstract

Phased or parasitic array antennas with complex feed mechanism are widely used to realize beam scanning. This paper presents a simple magnetized ferrite loaded circular waveguide antenna with three dimensional (3D) scan characteristics. Professional software is used to optimize the dimension and biasing requirement of the antenna. The required magnetizing fields (H 0 ) are tabulated to realize 60° of maximum beam scan in elevation plane for eight different azimuth regions covering 360°. A prototype of the high power waveguide antenna is fabricated to experimentally verify some of the simulated scan characteristics. Using LTCC technique, embedding the biasing coils within the ferrite cylinder can considerably reduce the H 0 values needed for 3D beam scan.
