ABSTRACT:
An antenna utilizes components of spatial harmonics to synthesis and shape radiation patterns. A counterpoise mounts a monopole radiator as well as a plurality of arrays of parasitic antenna elements excitable by the monopole radiator in a manner to produce the selected harmonics and consequently the desired radiation pattern. The parasitic antenna elements are compensated and are provided with switching to cause their activation. A cone radiator cooperates in exciting the parasitic antenna elements.
