This paper describes a singly-fed circularly polarized rectangular dielectric resonator antenna (RDRA) for MIMO and 5G Sub 6 GHz applications. Circular polarization was achieved for both ports using a novel-shaped conformal metal strip. To improve the isolation between the radiators, a “S” shaped defective ground plane structure (DGPS) was used. In order to authenticate the estimated findings, a prototype of the suggested radiator was built and tested experimentally. Over the desired band, i.e., 3.57–4.48 GHz, a fractional impedance bandwidth of roughly 36.63 percent (−10 dB as reference) was reached. Parallel axial ratio bandwidth of 28.33 percent is achieved, which is in conjunction with impedance matching bandwidth. Between the ports, isolation of −28 dB is achieved Gain and other far-field parameters are also calculated and found to be within their optimum limits

“…The degenerate mode pair of the fundamental mode TE y 1∂1 has been excited at 3 GHz while TE y 2∂3 and TE y 1∂5 are excited at 4.9 GHz and 5.4 GHz, as depicted in Figure 4. The high order mode promotes the circularly polarized excitation in the antenna [8,9]. However, due to the small bandwidth and mismatched between AR and the S 11 , further improvement on the antenna is discussed in the next section.…”

“…The mode degeneracy is disfavourable as it increases the cross-pol levels of an antenna and hence limits the antenna performance [5]. On the other hand, considerable attention had focused on the DRAs with circular polarization (CP) as they offered a better quality of signals, alleviate fading and multipath, insensitive to polarization mismatch, which makes them more suitable for wireless communication systems than the linearly polarized (LP) antenna [3,[6][7][8][9][10].…”

The paper presents a triband circular polarized rectangular dielectric resonator antenna. A single coaxial cable feeds the DRA to a double stub strip on the DRA side. A patch strip coupled to the feed assists in widening the bandwidth of the proposed DRA. The degenerate mode pair TE∂11x and higher-TE∂23x has been excited to achieve CP and enhance the antenna gain. The higher-order mode has been excited using a low-cost simple excitation mechanism without compromising on the size and shape of the DRA. An impedance bandwidth of 48% with a gain ~6–9 dBic was achieved in all resonance frequencies. Additionally, the AR bandwidth of 5.5%, 4.2%, and 2.76% was obtained at three different frequencies. Note that the proposed DRA exhibits a wide beamwidth of 112o, which is good for better signal reception. A comparison between the measured with simulated results shows that the measured results are matched by the simulated result trends.

“…The 5G NR is a multi-band spectrum and n79 (4.4–4.8 GHz) is one of the major focuses for future 5G communications in different parts of the world, such as China, the EU, and Japan [ 2 ]. In literature, different 5G antennas have been reported so far [ 3 , 4 ]. In the last few decades, the dielectric resonator antenna (DRA) has been acquiring a lot of attention from antenna researchers.…”

In this article, a rectangular dielectric resonator antenna (RDRA) with circularly polarized (CP) response is presented for 5G NR (New Radio) Sub-6 GHz band applications. A uniquely shaped conformal metal feeding strip is proposed to excite the RDRA in higher-order mode for high gain utilization. By using the proposed feeding mechanism, the degenerate mode pair of the first higher-order, i.e., TEδ13x at 4.13 GHz and TE1δ3y, at 4.52 GHz is excited to achieve a circularly polarized response. A circular polarization over a bandwidth of ~10%, in conjunction with a wide impedance matching over a bandwidth of ~17%, were attained by the antenna. The CP antenna proposed offers a useful gain of ~6.2 dBic. The achieved CP bandwidth of the RDRA is good enough to cover the targeted 5G NR bands around 4.4–4.8 GHz, such as n79. The proposed antenna configuration is modelled and optimized using computer simulation technology (CST). A prototype was built to confirm (validate) the performance estimated through simulation. A good agreement was observed between simulated and measured results.
