| Abstract: | Expressions for linearly-and circularly-polarized components of radiation field from radial antenna placed in arbitrary position on spherical satellite are derived. Computations are performed for radiation field of inclined and horizontal four-element array with turnstile excitation, and some typical patterns are shown. The effect of sphere radius and antenna length on the patterns, the requirements for earth station antenna as concerned with the field structures and, finally, the difference between radiation patterns for antennas on sphere and cylinder are discussed. |
