Abstract :
A (2 to 18 GHz) sinuous antenna has its performance measured and predicted using both the Numerical Electromagnetic Code (NEC) and the Patch Code for various tight spacings above a conductive ground plane. Spacings investigated were for physically realizable installations varying from 0.024 inch to 0.5 inch. Model limitations are addressed for comparison of measured to predicted data. Performance described includes antenna pattern shape, gain, and axial ratio. An assessment of the performance in the presence of tightly spaced ground planes is made.<>
