Given an array with defective elements, failure correction (FC) aims at finding a new set of weights for the working elements so that the properties of the original pattern can be recovered. Unlike several FC techniques available in the literature, which update all the working excitations, the Minimum-Complexity Failure Correction (MCFC) problem is addressed in this paper. By properly reformulating the FC problem, the minimum number of corrections of the whole excitations of the array is determined by means of an innovative Compressive Processing (CP) technique in order to afford a pattern as close as possible to the original one (i.e., the array without failures). Selected examples, from a wide set of numerical test cases, are discussed to assess the effectiveness of the proposed approach as well as to compare its performance with other competitive state-of-the-art techniques in terms of both pattern features and number of corrections.

“…It can be inferred from recent scientific publications on the development of phased antenna arrays for 5G applications [63][64][65][66][67][68][69][70][71][72][73][74][75][76] that array pattern synthesis requires the selection or evaluation of the following parameters and characteristics for the initialization of the synthesis procedure: the number of array elements, the aperture size, the separation between array elements (cell size), the array aperture lattice, as well as the detailed design of the individual array element including the relevant stack-up, polarization (single or dual per element), and spatial orientation along the radiating aperture. Such settings are aimed at system-level specifications and account for the adopted (or designed) beamforming integrated circuit (BFIC) solution and the host printed circuit board (PCB) manufacturing technology (including dimensional restrictions defined by the PCB design rules).…”

Electronically controlled antenna arrays, such as reconfigurable and phased antenna arrays, are essential elements of high-frequency 5G communication hardware. These antenna arrays are aimed at delivering specified communication scenarios and channel characteristics in the mm-wave parts of the 5G spectrum. At the same time, several challenges are associated with the development of such antenna structures, and these challenges mainly originate from their intended mass production, contemporary manufacturing technologies, integration with active RF chains, compact size, dense circuitry, and limitations in postmanufacturing tuning. Consequently, 5G antenna array designers are presented with contradictory design requirements and constraints. Furthermore, these designers need to handle large numbers of designable parameters of the antenna array models, which can be computationally expensive, especially for repetitive and adaptive simulations that are required in design optimization and tuning. Antenna array synthesis, namely, the process of finding positions, orientation, and excitation of the array radiators, is a challenging yet crucial part of antenna array development. This process ensures that the performance requirements of the antenna array are met. Therefore, there is a need for reliable yet fast automated computer-aided design (CAD) and synthesis tools that can support the development of 5G antenna array solutions, from the initial prototyping stage to the final manufacturing tolerance analysis. This paper presents an overview of recent advances in antenna array synthesis from the viewpoint of their applicability to the design of electronically reconfigurable and phased antenna arrays for wireless communications and remote sensing.

“…Hence, array antennas with a high gain are required to mitigate the propagation attenuation. Since a high gain leads to a narrow radiation beamwidth and thus limits the angular coverage, directional phased array antennas having an electrical beam-steering capability are usually proposed for implementation at both the base station and mobile device [5], [6]. Even though the basic issue of angular coverage can be mitigated by steering the beam, it remains challenging to achieve a sufficiently wide angular coverage using one phased array.…”

A compact low-profile phased array antenna unit with unidirectional hemispherical beamcoverage for 5G mm-wave applications is proposed in this paper. A four-subarray configuration is used for the proposed structure to achieve unidirectional hemispherical coverage in the boresight direction normal to the substrate. An artificial magnetic conductor (AMC)-backed slot antenna array with an optimal separation distance of 1.9 mm (= 0.31 λ at 28 GHz) is proposed as a subarray. The proposed antenna has increased Hplane beamwidth with the measured peak gain of 11.62 dBi and provides the desired wide inclined beam pattern in the elevation plane. The proposed antenna also offers steered beams over the range within ±45° in the azimuth plane. The hemispherical-coverage, phased array antenna unit composed of the four designed subarrays has overall dimensions of 80.8 mm × 80.8 mm × 2.4 mm. The coverage efficiencies of the proposed phased array antenna unit are 0.82, 0.71, and 0.61 for threshold gains of 5 dBi, 8 dBi, and 10 dBi, respectively, where the maximum solid angle is 2π steradians.
