“…It shows improvement over the UWB monopole without EBG, but still shows negative gain in part of the band. Two methods to increase the EBG surface bandwidth are to use progressive 6,7 or stacked EBG 8,9 structures that produce the required high-impedance surface over a broad band. The stacked EBG is chosen for the current UWB monopole.…”

“…EBG structures are usually periodic surfaces with high impedance, which makes them an interesting candidate to be placed close to a ground plane in various antenna engineering applications. EBG structures were realized to reduce and eliminate undesired surface waves in certain directions within the band gap, so maximum amount of EM waves get radiated into free space, which will increase the beamwidth, 7 radiation efficiency, and also provide higher gain 8 …”

This article presents a high gain cavity‐backed slot antenna using a perfect magnetic conductor (PMC) ground plane and multilayered superstrates. A textured surface of periodic pins is applied to realize a high impedance surface (HIS), which simulates a PMC ground plane. The main advantage of using this structure is to suppress the surface wave propagation, improve the input impedance matching, increase the bandwidth, control the side‐lobe levels, and also provide higher gain. Moreover, the multilayered superstrates has been used to enhance the antenna gain. The simulations and measurements for the S‐parameter, gain, and radiation patterns of the antenna are presented. The proposed cavity‐backed slot antenna offers a maximum gain of 18 dBi and an impedance bandwidth of 16.5% at 11.5 GHz.
