Microwave antenna array

Abstract

A teaching is specified for calculating the phase values for each aerial element of the antenna array required to generate a desired antenna directional characteristic, it being assumed that, for given amplitude shading, only the phase shading has to be calculated as the variable. In the past, it was only known for the beam deflection and beam widening to be achieved by phase control of aerial elements. A more wide-reaching beam modification, that is to say beam forming, is made possible for the first time by the invention. The invention can be used, for example, in electronically phase-controlled radar antennas. <IMAGE>
