ABSTRACT:
An antenna feed network implemented preferably in stripline for connecting the elements of a linear or planar array with a common port for transmit/receive operation. The network acts as a power divider/combiner and is entirely reciprocal. The network is realized in the form of a pattern of conductive traces on a single dielectric sheet of the stripline arrangement between parallel, spaced ground planes and does not require interconnections among multiple planes. The network may be utilized as a single or multiple beam forming network with the path lengths to the respective array radiators patterned to achieve a frequency scanning or beam normal array design.
