ABSTRACT:
A microstrip backfire antenna configuration combining the microstrip type tenna element with a waveguide cavity which provides control over the radiation pattern and obviates the need for a more expensive phased array antenna system; the microstrip element is placed in a waveguide cavity so as to excite both the microstrip element and the waveguide cavity in a predetermined manner.
