Analysis of an antenna composed of arbitrarily located slots and wires

A technique of analyzing an antenna composed of arbitrarily oriented thin wires and slots in a planar conducting screen is presented. The analysis is based on the generalized Hallen´s type integral equation with closed form kernel. A parametric evaluation is done for a configuration of slot and two bending wires (Clavin element). The results obtained are shown to be in close agreement with the experimental ones obtained by Clavin et al.
