“…To highlight the advantages of the proposed antenna, a comparison between the reported pattern reconfigurable phased antennas and the proposed design is summarized in Table 1. Ding and colleagues [16][17][18][19][20][21][22] can achieve the widest 3 dB beam scanning range, but the topology of the antennas makes them hard to be used in some conformal applications. The large diode number of the antenna unit used in Ding et al 16 greatly increases the cost and loss compared to the proposed design.…”

“…19,20 In a study by Iqbal et al, 21 the TM 11 and TM 21 modes are excited to generate the tilted beams by slots and posts loaded circular patch, the antenna can realize a wide beam scanning range with a low grating lobe, but the antenna unit needs an extra channel to excite the high order mode with different phase differences, which will greatly increase the cost of communication systems for the large size array. In the study by Chen et al, 22 a mixed-mode dielectric resonant antenna (DRA) is used to achieve the wide beam scanning range. The broadside and conical patterns are combined to implement the tilted beams.…”

In this article, a pattern reconfigurable antenna is proposed for wide beam scanning phased array applications. Different from the wide beamwidth unit design, the large beam scanning range of the proposed antenna array is realized by the reconfigurable radiation patterns with the different tilted angles of the antenna unit. The tilted beams can enhance the total beam coverage range of the antenna unit with high directivity, thus increasing the beam scanning range of the antenna array. The tilted beams are realized by the combination of the concentric circular and annular patch antennas. A PIN diode-loaded reconfigurable feeding network is designed to feed the patches with reconfigurable phase differences. The feeding network can achieve a good impedance matching effect and guarantee the symmetry of the tilted beams. To verify the beam scanning performance of the proposed antenna, a 1 × 4 linear array is fabricated and measured. The results prove that the antenna can achieve ±61°beam scanning range with ±78°3 dB beam coverage range and the maximum sidelobe level (SLL) of −8.0 dB. The characteristics include lowprofile, high efficiency, low SLL, and wide beam scanning range making it a very attractive choice for phased array antenna applications.

“…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 • ]. Arrays with wide element patterns are limited to spacings below 0.5λ to avoid emergence of grating lobes [10].…”

“…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.

In this paper, a novel beam‐controlling antenna based on a single‐layer digital coding metasurface (DCMS) is presented. A transmission‐type DCMS is placed in the near‐field of the source antenna to form a low‐profile structure with the height of 0.15λ0 in total. These DCMS elements have two kinds of particles with different transmissivity responses to y‐polarized wave, corresponding to two basic digital element 0 and 1 respectively. By designing the coding sequences on DCMS carefully, the radiating mode can be dynamically and real‐time controlled. The proposed antenna has multi‐function that can realize wide‐angle beam‐scanning and wide‐to‐narrow beam switching simultaneously. The scanning angle ranges from −85° to +85° in H‐plane with the gain fluctuation less than 2dBi. The simulation results are verified by experiments. This type of antenna can be applied in a variety of wireless communication systems with the outstanding advantages of low‐profile, low‐cost, and multi‐function.
