Abstract:
An antenna apparatus, comprising:at least a first curved reflector section and a second curved reflector section that define a compound curve antenna structure; a feed array including a plurality of feed elements comprising at least a first feed element in communication with said first and second curved reflector sections for use in providing at least one of a transmit beam and a return beam; and a control system communicating with said feed array for use in controlling said at least one of said transmit beam and said return beam, said control system including a memory storage for storing predetermined data related to controlling activation of said plurality of feed elements including at least said first feed element to provide a desired scan angle associated with said at least one of said transmit beam and said return beam; wherein said return beam at said desired scan angle includes electromagnetic (EM) radiation reflected from said first curved reflector section to said feed array, EM radiation reflected from said second curved reflector section to said feed array and EM radiation directly incident on said feed array without first striking said first and second curved reflector sections.
