"Isotropic" Coverage on Satellites of Large Diameter as Compared with Wavelength.

Nathaniel E. Feldman

ResearchPublished 1963

A description of techniques for wide angle coverage for use on satellites whose diameter is large compared with wavelength. The first method involves extending an antenna on a long mast. The second method provides "isotropic" coverage (i.e., through constant power over a sphere though of variable polarization) by using two extended balanced logarithmic conical spiral antenna elements, diametrically opposite and circularly polarized in the opposite sense as seen by an observer in the far field. The third method uses frequency diversity techniques
