Transmission-Line Characteristics of the Sectoral Horn

The sectoral horn is analyzed from the engineering viewpoint in such a manner as to make it feasible to consider it as one component of an over-all microwave transmission system. Equivalent network functions are derived and graphed which are based on the consideration of the sectoral horn as a nonuniform transmission line. The resulting curves should be useful to those designing systems containing sectoral-horn components. The physical significance of the derived normalized functions is discussed, and the applicability of network philosophy is pointed out.
