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