Abstract

Characteristics of Ni ferrite based microstrip phased array antenna in terms of the switchability, radiation patterns and gain have been investigated using transmission line model. The radiation characteristics of antenna are described with a normal magnetic bias field towards the plane of ferrite substrate considering the phase excitation difference between the patch elements π/2 and π/4. It is observed that by properly varying the relative phases, it is possible to steer the direction of radiation. This advantage is applicable in radar, search/track applications.
