“…Since no conformal DRA arrays are found, the planar DRA arrays [13,14,24] and conformal microstrip [25][26][27] are included. Compared with the DRA arrays in [13] and [24], the proposed structure shows higher gain and lower SLL. Although the array in [14] owns a wider bandwidth and lower SLL, a reflector has to be applied to obtain directional radiation pattern.…”

“…However, since the air gap between the double-layer dielectric substrates is difficult to control, the measurement errors can be caused easily. In [12] and [13], SIWfed DRA arrays are presented. However, due to SIW feeding technique, the bandwidths are narrow (< 9%), and the SLLs are unsatisfied (about −10 dB).…”

A novel conformal dielectric resonator antenna (DRA) array based on aperture-coupled series-feeding approach is presented for wireless communication. The antenna is composed of eight curved width-gradated DRA elements with a simple feeding structure. The proposed design presents a tapered current amplitude distribution by using DRA element width gradation method, and low side-lobe level (SLL) characteristic can be obtained. Besides, an extra matching line is inserted into the single feeding line to realize better impedance characteristic. To validate the performance of the proposed design, the conformal array is fabricated and measured in an anechoic chamber. The measured impedance bandwidth (|S 11 | < −10 dB) of the fabricated prototype is from 5.78 GHz to 5.87 GHz. At 5.8 GHz, the antenna offers a measured peak gain of 14.75 dBi and SLL of −19.3 dB. The polarization discriminations of the array on Eand H-planes are greater than 20 dB. The measured results of the fabricated prototype demonstrate that the proposed design has the potential to be applied to wireless communication system with curved surface.

This paper presents a novel dual slant polarized antenna for millimeter-wave (mmWave) base stations. Compared with the traditional slant polarized mmWave antennas, the proposed antenna offers the advantages of high cross-polarization discrimination (XPD), good aperture efficiency, simple structure, and low profile. The corner-fed substrate integrated waveguide (SIW) cavity is adopted to improve the port isolation and XPD of this slot-coupled antenna. Four corner-truncated patches connected by a thin cross strip are placed over the SIW cavity to increase the operation bandwidth. Then, a 2 × 8 antenna array is designed to exemplify the antenna element performance. To improve impedance matching, a shorted patch is introduced in designing the series feeding network and the power divider. The experimental results show that the 2-dB-down gain bandwidth of the proposed antenna array reaches 6.0% and the port isolation is better than 20 dB. The gain and XPD of the antenna array measure 16.7 dBi and 25 dB at the center frequency, respectively.

“…Several slant polarised and dual-slant polarised antennas have been reported [17,[20][21][22]. More recently, a substrate integrated waveguide fed DRA array with 45° slant polarisation has been reported and investigated in [23]. However, to the best of the author's knowledge, the dual-slant polarised antenna based on DR has not been reported earlier in the literature.…”

In this study, two types of dielectric resonator antennas (DRAs) with dual‐polarisation are proposed and investigated for multiple‐input multiple‐output (MIMO) applications. The first design is a dual‐slant polarised DRA and exhibits the measured impedance bandwidth of 8.2% (5.27–5.72 GHz) and 11.2% (5.05–5.65 GHz) for Port1 and Port2, respectively. Across the operating frequency band, the isolation between the input ports is better than 22 dB and the measured gain of the antenna varies in the range of 5.99–6.38 dBi. The second design developed here is a dual‐linearly polarised DRA which is able to provide horizontal and vertical polarisations and is realised by integrating a two‐stage rat‐race coupler with the DRA for excitation purpose. In this case, the measured impedance bandwidths are 11.81% (5.18–5.83 GHz) and 15.18% (4.93–5.74 GHz) for Port1 and Port2, respectively, and the inter‐port isolation is better than 20 dB throughout the operating frequency band. The antenna exhibits the measured gain variation of 5.94–6.48 dBi for Port1 and 5.54–5.86 dBi for Port2. Furthermore, for both the antennas, the envelope correlation coefficient is below 0.0004 throughout the bandwidth and the total active reflection coefficient is better than −10 dB, confirming the good diversity and radiation performance.
