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
