É apresentada a formulação da admitância de parede de uma antena circular de microfita pelo método do domínio espectral. A antena circular de microfita é calculada usando o modelo de cavidade. Os campos eletromagnéticos dentro da cavidade da antena são determinados a partir da condição de contorno da impedância na abertura lateral. A contribuição da região externa à antena é levada em consideração pela admitância da parede. A admitância da parede é definida pelo campo magnético produzido pela corrente magnética equivalente na abertura. O campo magnético é calculado pelo método do domínio espectral. As admitâncias da parede obtidas por este método são comparadas com os resultados calculados por Shen. As impedâncias de entrada calculadas da antena microfita concordam bastante bem com os dados experimentais para a espessura do substrato de até 0.048λg. A formulação de admitância de parede apresentada aqui é facilmente aplicável a antenas microfita de formato arbitrário.

Abstract: The formulation of the wall admittance of a circular microstrip antenna by the spectral domain method is presented. The circular microstrip antenna is calculated using the cavity model. The electromagnetic fields within the antenna cavity are determined from the impedance boundary condition at the side aperture. The contribution from the region outside the antenna is taken into account by the wall admittance. The wall admittance is defined by the magnetic field produced by the equivalent magnetic current at the aperture. The magnetic field is calculated by the spectral domain method. The wall admittances obtained by this method are compared with the results calculated by Shen. The calculated input impedances of the microstrip antenna agree fairly well with the experimental data for the substrate thickness of up to 0.048λg. The formulation of wall admittance presented here is easily applicable to arbitrarily shaped microstrip antennas.
