“…As illustrative examples, polarizing screens are typically built from arrangements of cascaded meander-line gratings or other elements providing similar RF performance [3,4].The implementation of screens for Wide Angle Impedance Matching (WAIM) in phased arrays is typically addressed employing simple dielectric slabs or more sophisticated metamaterials and dielectric lenses [5][6][7].…”

This contribution concentrates on the conception of periodic structures that are built from metallic three-dimensional unit-cells. Such arrangements allow synthesizing diverse functionalities such as polarization conversion, frequency filtering, and impedance matching. In addition, the topologies considered here can be built monolithically employing only metal, therefore providing multiple advantages, such as low insertion losses, high power handling and manufacturing certainty.

“…In this way, the IAB node would be composed of only two antennas (instead of three) to provide omnidirectional coverage, hence reducing the overall hardware cost. The realization of a 180 • -scanning antenna system is challenged by system-level aspects, as the antenna has now to serve a larger FoV with same performance of the three-sector case, as well as hardware-level issues, since the development of an antenna with a 180 • FoV requires innovative EM design techniques like conformal arrays [31], deflecting lenses [32], metasurfaces [33], reconfigurable pattern radiating elements [34] and wide-pattern radiating elements suitable for phased arrays [35].…”

Fifth generation (5G) and beyond communication systems open the door to millimeter Wave (mmWave) frequency bands to leverage the extremely large operating bandwidths and deliver unprecedented network capacity. These frequency bands are affected by high propagation losses that severely limit the achievable coverage. The simplest way to address this problem would be to increase the number of installed mmWave base stations (BSs), at the same time augmenting the overall network cost, power consumption and ElectroMagnetic Field (EMF) levels. As alternative direction, here we propose to complement the macro-layer of mmWave BSs with a heterogeneous deployment of Smart Electromagnetic (Smart EM) Entities -namely IAB nodes, Smart Repeaters, Reconfigurable Intelligent Surfaces (RISs) and passive surfaces -that is judiciously planned to minimize the total installation costs while at the same time optimizing the network spectral efficiency. Initial network planning results underline the effectiveness of the proposed approach. The available technologies and the key research directions for achieving this view are thoroughly discussed by accounting for issues ranging from system-level design to the development of new materials.

“…Changing the phase of the elements on the phase shifting surface is often difficult or can result in transmission losses due to its small size or complex structure. Therefore, some scholars have studied in using phased array to irradiate the transmitarray, which is designed with artificial materials 65,66 or dielectric lens, 67 to achieve wide scanning angle and high gain. The proposed transmitarray can perform continuous beam scanning by dynamically adjusting the amplitude and phase distribution on the phased array aperture.…”

As the application of microwave to radar and 5G communication goes wider, the array beam scanning capability has become an important and popular issue in modern society. Appropriate implementation of beam scanning methods suitable for diverse conditions could provide better performance and help to save costs for a system. Moreover, electronically scanned array has the characteristics of fast beam switching rate, high measurement accuracy and low profile. Thus, discussions on typical electronic scanning approaches are particularly necessary. This paper first presents a review of typical electronic scanning approaches to microwave arrays, such as the phased array, the focused aperture array, the frequency scanning array, and the time modulated array. And then some latest designs in the industry have been introduced. In addition, problems appeared in the application of the phased array and relevant solutions have been put forward. For the rest, some discussions are briefly summarized, as well as some comments on future trend in this field.
