ABSTRACT:
An antenna element architecture containing a dielectric beamwidth compensation perimeter structure around a radiating element is disclosed. A transmitting and receiving antenna element is provided so as to provide a desired azimuth and elevation radiation pattern in the intended polarization without degrading performance of cross polarization. Both single and dual polarization antenna elements can be employed.
