ABSTRACT:
A method of reducing blockage in a reflector antenna includes disposing a feed mechanism in front of a first reflector and disposing a second reflector in front of the feed mechanism. The second reflector permits energy to pass that would otherwise have been blocked from being received or transmitted by the first reflector. A reflector antenna is also formed in accordance with this method. Another method of reducing blockage in a reflector antenna includes disposing a first feed mechanism in front of a first reflector and disposing a second antenna in front of the first feed mechanism. The first feed mechanism blocks energy from being received or transmitted by the first reflector. The second antenna receives or transmits energy blocked by the first feed mechanism. A reflector antenna is also formed in accordance with this method.
