Abstract :
Moment-method oriented singular integral equation techniques are used for the exact analysis of parallel plate-fed slot antennas loaded by a dielectric semicylinder. Both for TM and for TE incident-mode excitations, high-order acceleration techniques are developed that help recast all matrix elements into rapidly converging series. This, in conjunction with the small matrix sizes required, enables one to obtain extremely accurate results with low computational cost
