Abstract
A bow-tie slot panel antenna is described, having a parasitic element positioned at an orientation from the slot to generate orthogonal fields. By adjusting the coupling ratios, dimensions and angle of orientation of the parasitic element, circularly polarized fields can be effectively produced, using the panel antenna as the primary radiator.
