Approximation Techniques for the Mutual Admittance of Slot Antennas on Metallic Cones.
Abstract
The effect of scattering from a sharp tip on mutual admittance is investigated for pairs of circumferential and radial slots on a semi-infinite metallic cone. Mutual coupling measurements as a function of frequency and angular separation are presented and compared with numerical calculations. The base of the conical model used in the experimental study was terminated in a spherical cap to minimize scattering from the infinite length of apparatus. The circumferential slot results illustrate interference effects between the direct coupling from slot-to-slot via the geodesic path over the conical surface and the tip back scattering. For the radial slot configuration, the results exhibit negligible tip scattering effects. (Modified author abstract)
