Abstract : A loop antenna is simulated by four end-fire arrays. The effects of three methods to increase the intensity of the E(tan) component of radiation near a conducting ground are shown. The theoretical basis for the three methods are given. A combination of two of the methods, namely, trapped modes in a dielectric slab excited by a parallel plane waveguide, given field patterns with major lobes near the plane of the ground. This combination shows promise of giving a gain of 14 db near the plane of a finite ground if no limitations on the length of dielectric are imposed. (Author)
