“…However, if highly directive beams are adopted both at the TX and RX side, the wireless communication system will suffer a large beam setup time. To overcome this issue, the adaptive beamwidth approach has been proposed [175]. First, the TX and RX find their angular sectoral by using a wide beam.…”

A review of technological solutions and advances in the framework of a Vertical Heterogeneous Network (VHetNet) integrating satellite, airborne and terrestrial networks is presented. The disruptive features and challenges offered by a fruitful cooperation among these segments within a ubiquitous and seamless wireless connectivity are described. The available technologies and the key research directions for achieving global wireless coverage by considering all these layers are thoroughly discussed. Emphasis is placed on the available antenna systems in satellite, airborne and ground layers by highlighting strengths and weakness and by providing some interesting trends in research. A summary of the most suitable applicative scenarios for future 6G wireless communications are finally illustrated.

“…It is worth noting that the study in [57] and most of the current work on the matched filtering precoding or grid-of-beams use periodic array topologies with high side lobes on average. However, it can be seen that literature is very rich regarding the aperiodic array synthesis techniques [147]- [155] and the multidisciplinary system advantages (on the link quality, computational burden, thermal management etc.) brought by the array layout irregularity [45], [156]- [162].…”

Orthogonality in multibeam antennas is revisited. The difference between orthogonal beamforming and zero-forced beamforming is highlighted. The intriguing relation between orthogonality, reciprocity and losses is recapitulated. Different approaches on the design of orthogonal beamforming networks and implementation of zero-forced beamforming strategies are shown with various examples from the antenna-research-oriented literature. The use of orthogonal and zero-forced beamforming is discussed from the communication system perspective with relevant studies from diverse disciplines. Some of the future research challenges and potential benefits are outlined for the next generation satellite and cellular communication applications.

“…Concentric ring array (CRA), which has the symmetrical structure of a circular array, ensures that its beam and antenna gain performance are basically maintained in a certain range, and it can relatively achieve mutual coupling balance. Tese excellent properties have made it the subject of intensive investigations in recent years [1][2][3][4]. In particular, array synthesis patterns with arbitrary element positions have attracted more attention [5,6].…”

In this paper, an effective synthesis method for sparse uniformly excited concentric ring array (CRA) element positions featuring a minimum sidelobe level (SLL) is presented. This method is based on the chaos sparrow search algorithm (CSSA), which can search for the optimal solution under multiple constraints. By improving the constraint on the number of array elements on each ring, the solution range of the optimal solution is further reduced, and the global search ability of the algorithm is effectively improved by introducing tent mapping into the algorithm to initialize the population. Numerical examples are presented to assess the effectiveness and reliability of the proposed method, showing that it can achieve better results than existing methods in the design of sparse concentric ring array arrangements.
