Abstract :
Exterior admittances, calculated with a body of revolution (BOR) moment-method solution, are used with the disk cavity Green´s function to calculate the input impedance to various probe-fed circular microstrip patch geometries via the induced EMF method. The main advantage of the method is its ability to analyze general, rotationally symmetric patch configurations. The tradeoff associated with this generally is increased CPU time, which is strictly a function of the complexity/size of the exterior BOR region. Accuracy of the solution is good to within 1% in resonant frequency for the thick and thin substrate cases considered.<>
