Abstract: A hybrid circuit module having first and second pairs of input terminals and four output terminals. First, second, third and fourth baluns each include first and second transmission line wires. The baluns are configured between the input and output terminals to isolate sources when placed across pairs of input and output terminals. An antenna system is formed with the hybrid circuit module and a plurality of radiators. The circuit module may be configured to simultaneously generate or receive two or more independent radiation patterns. A method is provided for feeding a multiarm antenna structure with a hybrid circuit network. The method includes the steps of symmetrically positioning a conductive element with respect to all of the arms, and coupling terminals of the antenna arms to the network through a conductive element. Alternately the second terminals may be electromagnetically coupled to the network without requiring the conductive element.
