Abstract : A slot antenna mounted symmetrically in the center of a square plate will radiate a symmetrical antenna pattern. When the slot is moved to any other location the pattern will be unsymmetrical. The degree of symmetry degradation for various locations of a slot on a 2' by 2' square plate at approximately 1 GHz and 3 GHz is the subject of this investigation. To make the pattern calculations well-known first-order principles of the geometrical theory of diffraction (GTD) are used. A user oriented computer program is presented in the appendix and its limitations discussed. (Author)
