“…It is clearly seen that, for the short-circuited patch antenna, the input impedance become very sensitive to the feed position and strongly depends on the distance between the shorting post and the feed position [2][3][4][5][6][7][8][9][10]. The determination of all relevant parameters for the shorting post microstrip patch antenna is straight forward once the resonant frequency has been determined.…”

“…Among various antenna bandwidth enhancement configurations, the two gap-coupled circular microstrip patch antenna is most elegant one. So, gap-coupling is the suitable method for enhancing the impedance bandwidth of the antennas [6,7]. In the cofigration of gap-coupled microstrip antennas method, two patches are placed close to each other.…”

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.

“…Earlier in the literature, compact microstrip antennas (MSAs) were realized by using higher dielectric constant substrates, shorting post/plate, inserting the different shape of slot into the patch . Broadband MSAs were also realized by different techniques of the multi‐resonator or hybrid gap‐coupled configurations, electromagnetically coupled stacked configurations, capacitive coupling, and so on . The size of broadband configurations is reduced by gap‐coupling the split patches .…”

Half‐hexagonal microstrip antenna (H‐HMSA) is a compact version of HMSA, as it resonates at the same fundamental mode frequency. In this article, a compact configuration of a single layer, broadband gap‐coupled H‐HMSA has been proposed. Gap‐coupled H‐HMSA is fed indirectly by a λ/2 microstrip‐line resonator. Broad bandwidth (BW) is achieved with an effective use of resonance introduced by λ/2 resonator and gap‐coupled half‐hexagonal radiating patches. A peak gain of 7.07 dBi and measured BW (S11 ≤ −10 dB) of 11.5% at the center frequency of 5.2 GHz have been achieved, which occupies a small volume of 0.023 λ03 including the ground plane. The radiation patterns remain in the broadside direction throughout the return loss BW. Simulated results of the proposed antenna configuration are experimentally validated with good agreement.
