“…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.…”

“…Although the array in [14] owns a wider bandwidth and lower SLL, a reflector has to be applied to obtain directional radiation pattern. Besides, since the designs in [13,14,24] are planar DRA arrays with large sizes, they are not suitable for the actual application with curved surface. For the conformal arrays, the design in [25][26][27] offers a compact structure with low profile, but the gains and SLLs are needed to be improved.…”

“…Recently, to fulfil the demand for high gain antenna, high-gain DRA arrays have been widely studied [8][9][10][11][12][13][14]. In [8], a high-gain DRA array fed by a radial-line waveguide is presented.…”

“…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.

“…In [26], a stacked structure has been used to increase the antenna bandwidth to 18.2%, but at the cost of a higher antenna profile. In [27][28], the parasitic elements are used to enhance the DRA bandwidths. For instance, the bandwidth of DRA is increased 4.5% by using two parasitic elements in [27].…”
