“…The simulation is performed by using the Method of Moment based commercially available simulator IE3D. In [23], an expression for the resonant frequency of two gapcoupled circular microstrip patch antennas loaded with shorting post is derived by using the similar approach as in [22]. It is shown that such combination leads to a very accurate model of the two gap-coupled circular microstrip antennas loaded with shorting post.…”

In this paper, a technical review on gap-coupled microstrip antennas is presented. The gap-coupled microstrip antennas give a large bandwidth as compared to the conventional microstrip antennas. The method of bandwidth enhancement using gap-coupled microstrip antennas has been elaborated. The gap-coupled microstrip antennas also produce two resonances. The dual frequency operation of the gap-coupled microstrip antenna is also described. A research overview of gap-coupled microstrip antennas, challenges, types of gap-coupled microstrip antennas as well as numerical methods of calculating various parameters of the gap-coupled microstrip antennas are discussed in this paper.

“…Increase of the bandwidth of this type of the antenna, in general, requires reducing the substrate permittivity or increasing its thickness, since the exact shape of the patch does not have a dominant effect on the bandwidth if the overall dimensions are similar. Using the gap-coupled resonators, the bandwidth of the microstrip antennas can be increased [2][3][4][5]. Recently, researchers have presented a bandwidth enhancement method for low profile E-shaped microstrip patch antennas in [6].…”

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.
