“…The H-fields (x–z plane) of the proposed DRA at the resonance frequencies are given in Figure 9 . The analysis is similar with that in [ 42 ]. With reference to Figure 9 a, the typical H-field of the HEM 111 y mode was found at 3.56 GHz, which has one energy concentration zone inside the DRA.…”

A broadband differential-fed dual-polarized hollow cylindrical dielectric resonator antenna (DRA) is proposed in this article. It makes use of the HEM111, HEM113, and HEM115 modes of the cylindrical hollow DRA. The proposed DRA is simply fed by two pairs of conducting strips and each pair of strips is provided with the out-of-phase signals. After introducing four disconnected air holes into the DRA, a broadband characteristic is achieved, with little effect on the antenna gain of its higher-order modes. To verify this idea, frosted K9-glass is applied to fabricate the hollow cylindrical DRA. The differential S-parameters, radiation patterns, and antenna gain of the DRA are studied. It is found that the proposed differential-fed dual-polarized DRA is able to provide a broad differential impedance bandwidth of ~68% and a high differential-port isolation better than ~46 dB. Moreover, symmetrical broadside radiation patterns are observed across the whole operating band. The proposed DRA covers the frequency bands including the 5G-n77 (3.4–4.2 GHz), 5G-n79 (4.4–5.0 GHz), WLAN-5.2 GHz (5.15–5.35 GHz), and WLAN-5.8 GHz (5.725–5.825 GHz), which can be used for 5G communications.

In this article, a compact dielectric resonator antenna (DRA) with partial ground plane for wireless applications is examined. The exhibited structure is fed by a microstrip line. To demonstrate the functionality of a tri-band, a circular dielectric resonator antenna with concentric circular rings is created. The developed antenna parametric analysis has been performed on HFSS platform. The configured design operates at three frequency bands, i.e., 1.98-2.59 GHz (ISM), 3.24-3.85 GHz (Wimax), and 4.85-5.85 GHz (WLAN), with the fractional bandwidths of 26.6%, 20.4%, and 18.67%, respectively. The customized concentric rings are placed onto the substrate to reinforce the antenna appearance and also miniaturize the size. The measured outcomes are strongly in accordance with the simulated results. The designed model can be customized with certain attributes to wireless applications.

In this study, the authors present the design of a half H-shaped dielectric resonator antenna (DRA) for compact size and wide bandwidth. The trapezoidal patch feed is used to excite the DRA, which results in TE 113 Y and TE 115 Y resonant modes of the rectangular DRA (RDRA). It is found that the broad-side higher-order TE 113 Y with the TE 115 Y mode is used in the proposed design to make it wideband. The effective dielectric constant of the proposed DRA is reduced by the slots and then the structure is made half to make it compact. Finally, for further improvement in bandwidth, the size of the ground plane is reduced, which increases the parallel capacitive reactance and decreases the Q-factor. The proposed structure achieves measured impedance bandwidth S 11 ≤ −10 dB of 75% (4.30-9.50 GHz) with a maximum gain of 7.20 dB. The proposed DRA is applicable for WLAN (5.15-5.72 GHz) and orthogonal frequency-division multiplexing 802.11a (5.72-5.85 GHz).
