“…The proposed antenna that combines SIW and a DRA outperforms the same U-shaped slot/cut SIW antenna in [ 20 ] in terms of bandwidth performance and multiple resonances. Moreover, for SIW and DRA work, the proposed triple band SIW with a DRA has more selections of frequency switching and a wider bandwidth than the single band antennas in [ 9 , 11 , 12 ] and a dual-band antenna in [ 10 ]. The proposed single port triple band SIW with a DRA antenna is backward compatible with 4G bands and also supports the sub-6 GHz band for future 5G wireless communication systems.…”

“…Dielectric Resonator Antennas (DRAs) are used extensively in the electromagnetic field in comparison to microstrip antennas because of their superior qualities such as higher radiation efficiency, higher gain, and greater bandwidth [ 8 ]. Several research works using the combination of SIW and DRA in a single port have been reported in [ 9 , 10 , 11 , 12 , 13 ]. It can be concluded that a substantial amount of work has been conducted on rectangular DRAs since they provide one extra degree of freedom over cylindrical and two degrees of freedom over hemispherical DRAs [ 8 ], resulting in easier bandwidth control.…”

“…They modified the antenna having an operating frequency of 5.33 GHz and 4.9dBi gain by placing different dielectric resonators on the slot. Cylindrical shaped and rectangular dielectric resonators provided a 700 MHz bandwidth enhancement and a hemispherical shape produced a 660 MHz enhancement [13]. Although their research used dielectric resonators, these dielectrics were not applied to the cavities.…”

“…Most of these implementations involve the use of structures that contribute to the complexity of the printed monopole antenna. Further, the use of dielectric resonators (DRs), which are made of low-loss materials with high permittivity, has been one of the proven ways to increase the bandwidth of microstrip antennas [ 25 ]. However, this method increases the losses of the antenna, which may degrade its radiation efficiency.…”
