Multi-shaped-beam reflector antenna.

摘要

A reflector antenna (1, 2) generates two (3, 4) or more beams which are separated angularly in the elevation plane, as in multi-beam antennas, and shaped so as to provide when combined any desired pattern of the radar coverage.

Important features of this antenna are:
- reduction of the vertical size of the reflector which is only 20% higher than a reflector designed to obtain the total coverahe by means of a single shaped beam;- considerable constructional semplicity with respect to the type of antennas used at present to meet the same above mentioned features.
