“…Currently, there are a variety of studies that consider the element pattern as part of the array design. The first design option is to widen the single-element pattern to achieve larger steering range [1]- [6]. The other option is to use patternreconfigurable elements [7]- [11] for larger beam steering range in the vertical plane θ = [−90 • , +90 • ].…”

“…Additionally, larger steering angles are required when the base station density increases [14], which will be a growing trend due to 5G. Since only a limited steering range is required, the aforementioned arrays with pattern reconfigurable elements [7]- [11] instead of arrays with wide element patterns [1]- [6] are a better choice for base stations and other similar applications. Reconfigurable elements allow concentrating the radiation only in the steering range of interest, whereas elements with wide element patterns are designed to radiate equally in all directions.…”

In this paper, we present a novel method to tailor the radiation pattern of an antenna element, such as a single element of an array, by maximing its partial radiation efficiency in the desired angular space. The tailored pattern of the single element is achieved by current distribution synthesis using multiple feed points in the antenna. A method to determine and realize the currents at the feeds is presented. The method is demonstrated by designing and manufacturing a four-element linear array consisting of tailored antenna elements and comparing its performance to the reference case. The element consists of four closely-spaced metallic patches placed on a substrate backed with a ground plane, and each patch is separately fed. The initial four-port feed is reduced to a single feed with a feeding network based on the determined currents. A conventional patch antenna is chosen as the reference. The simulated and measured results show improvement in the realized gain in the desired angular space.

A dual-polarized wide-beam (DPWB) antenna is optimized by a hybrid topology optimization (HTO) method, which combines the scalar isotropic material with penalization and the level set method. The HTO method has high optimization freedom degree, strong topology-searching ability and fast convergence speed. The initial model of the antenna is designed as a dual-feeding square microstrip patch antenna with short-circuit metal walls around the patch. By optimizing the metal patch on the upper side of the model, the DPWB antenna is obtained. The DPWB antenna is symmetric with respect to both ports. When fed to either port, the half-power beamwidth of the DPWB antenna can reach 166 (À82 ~84 ) in the E-plane and 124 (À62 ~62 ) in the H-plane. The performance is verified by both simulation and measurement. The DPWB antenna is further applied to a linear phased array, reaching an E-plane scanning angle range of 160 (À80 ~80 ) and an H-plane scanning angle range of 122 (À61 ~61 ), with the gain fluctuation less than 3 dB and the sidelobe level less than À10.1 dB.

“…Many types of antenna elements have been used to design wide‐angle scanning phased arrays. In [2–4], some wide‐beamwidth microstrip antennas with hybrid patch modes are used as antenna elements for phased arrays. However, these antenna elements have the same disadvantage of narrow bandwidth, causing the narrow bandwidth of the phased arrays.…”

A wide‐beamwidth dielectric resonator antenna with small radiator is used to design a wide‐angle scanning phased array. The proposed dielectric resonator antenna element uses concave structure for wide‐beamwidth, and the metal patches on the top of the dielectric resonator are used to reduce the size of radiator. The simulated half‐power beamwidth of dielectric resonator antenna is 157.8° and 140.9° in the E‐ and H‐planes, respectively, while the size of the radiator of the dielectric resonator antenna is only 9.7 × 9.7 × 10 mm3 (0.162λ0 × 0.162λ0 × 0.167λ0). One 1 × 8 linear phased array is designed based on the dielectric resonator antenna element. Due to the small size of dielectric resonator radiator, the mutual coupling between the array elements is very small and each element in the array has the similar radiation pattern with wide‐beamwidth. Because of these critical features, the phased array can scan from −67° to +67° with a gain fluctuation less than 1 dB and a maximum side lobe level less than −10 dB. Measurement results agree well with simulation.
