Abstract: In this paper, theoretical analysis of the input impedance of the two gap-coupled circular microstrip path antennas loaded with shorting post has been performed. The concept of coupled microstrip lines is applied to the gap-coupled microstrip antennas loaded with shorting post and using circuit theory approach the input impedance of the structure is calculated. The effect of mutual coupling between the radiating apertures has been taken into account. Simulated results are presented for input impedance of the gap-coupled circular microstrip patch antenna loaded with shorting post which supports the theoretical predictions. The simulation work has been performed using the method-of-moment based commercially available simulator IE3D. The comparison shows good agreement between simulated and numerically computed results
