Abstract :
A closed form expression for the series reactance of an electrically small aperture in the center conductor of a microstrip line is determined using equivalent dipole moments due to the aperture and employing a quasistatic approach. The reactance of an inclined slot and a diamond shaped aperture are evaluated as a function of the aperture geometry in the lower microwave frequency band. The results based on this analysis are compared with those obtained from Oliner´s formula. Experimental results are in fairly good agreement with the results obtained using the proposed theory
