Disipación de potencia en redes en celosía: la radiación del strip-slot complementario

Abstract

A circuit property of symmetrical lattice networks is derived and applied to the analysis of symmetrical twoport electromagnetic structures. This property is related to the independence of the power dissipation in the series and cross impedances of the lattice network and the consequent independence in the power dissipated under even and odd excitation in the twoport structure. Its utility is illustrated with its application to a planar radiating element, the so-called complementary strip-slot. This property allows identifying the cause of the losses in the analysed example and explains the radiation origin.
