Abstract
An antenna feed for a TACAN circular array. A power divider divides a source of radio frequency signals into zero, first and ninth order mode signals. A second power divider divides the zero mode input signal into a plurality of output signals each driving a pair of elements of the TACAN array. A second conventional matrix of radio frequency components receives the first and ninth mode excitation signals. A phase combining network combines the first and ninth mode signals so as to produce a plurality of signals each driving a pair of antenna elements. An output hybrid coupler combines the zero phase mode with the phase combined signals to produce the required TACAN azimuth antenna pattern.
