INITIAL INVESTIGATION OF MONOPOLE ANTENNA SYSTEMS FOR USE ON SPHERICAL METAL SATELLITES
Abstract
To obtain improved omnidirectional tracking, telemetry, and command communication coverage for future satellites, several monopole antenna systems were investigated with a view to minimizing nulls in the antenna pattern coverage. A conventional modified turnstile antenna used on spherical satellites, and various unconventional arrangements of feed and passive monopoles in pairs were investigated. Two different monopole arrangements provide a 10 db improvement in antenna pattern nulls as compared to the conventional turnstile. These results imply that the turnstile technique can be improved and that the 2 systems recommended here are worthy of further consideration. (Author)
