“…Unlike electronic reconfiguration, the optical technique has constraints for lossy behavior and complex activation mechanisms, while the mechanical technique confronts a slow response [36][37][38][39], but the best are these two tend to perform without require biasing lines. The material change technique exhibits low profile and lighter weight but, unfortunately, had limited application [40,41].…”

New requirements in communication technologies make it imperative to rehash conventional features such as reconfigurable antennas to adapt with the future adaptability advancements. This paper presents a comprehensive review of reconfigurable antennas, specifically in terms of radiation patterns for adaptation in the upcoming Fifth Generation (5G) New Radio frequency bands. They represent the key of antenna technology for materializing a high rate transmission, increased spectral and energy efficiency, reduced interference, and improved the beam steering and beam shaping, thereby land a great promise for planar antennas to boost the mid-band 5G. This review begins with an overview of the underlying principals in reconfiguring radiation patterns, followed by the presentations of the implemented innovative antenna topologies to suit particular advanced features. The various adaptation techniques of radiation pattern reconfigurable planar antennas and the understanding of its antenna design approaches has been investigated for its radiation pattern enhancement. A variety of design configurations have also been critically studied for their compatibilities to be operated in the midband communication systems. The review provides new insights on pattern reconfigurable antenna where such antennas are categorized as beam steering antenna and beam shaping antennas where the operation modes and purposes are clearly investigated. The review also revealed that for mid-band 5G communication, the commonly used electronic switching such as PIN diodes have sufficient isolation loss to provide the required beam performance.

“…Despite all these advantages, the flexibility of this type of antenna is limited, and it is difficult to provide multi-function reconfigurable characteristics. In addition, its performance has a slow response and requires a power source with complex integration [81,82]. For the antenna systems which do not require fast reconfiguration, this approach is an attractive technique.…”

Due to the fast development of wireless communication technology, reconfigurable antennas with multimode and cognitive radio operation in modern wireless applications with a high-data rate have drawn very close attention from researchers. Reconfigurable antennas can provide various functions in operating frequency, beam pattern, polarization, etc. The dynamic tuning can be achieved by manipulating a certain switching mechanism through controlling electronic, mechanical, physical or optical switches. Among them, electronic switches are the most popular in constituting reconfigurable antennas due to their efficiency, reliability and ease of integrating with microwave circuitry. In this paper, we review different implementation techniques for reconfigurable antennas. Different types of effective implementation techniques have been investigated to be used in various wireless communication systems such as satellite, multiple-input multiple-output (MIMO), mobile terminals and cognitive radio communications. Characteristics and fundamental properties of the reconfigurable antennas are investigated. writing-review and editing, N.O.P. and R.A.A.-A.; investigation, N.O.P., H.J.B., Y.I.A.A.-Y. and A.M.A.; resources, N.O.P. and R.A.A.-A.; for other cases, all authors have participated.

“…These elements have been distributed as close as possible taking into account the width of the WR51 outputs and that the wall between adjacent outputs should have a thickness of 1 mm so that the CWFN could be machined. It must be highlighted that although the use of dielectric parts could be considered as not compatible with aerospace applications, the presented ASPA could be replaced by other radiating structures such as cavity slots at the end of the waveguide outputs [22]. However in the presented prototype this substrate based array has been used since the authors were interested in providing reconfiguration capabilities to the design in [26].…”

“…In this field, Tuning Screws (TS) have been extensively used in the last decades to tune filters [19] or to implement reconfigurability in waveguide devices [20], [21]. Recently, this technique has been proposed by the authors to implement reconfiguration in waveguide array antennas [22]- [24] achieving satisfactory results in terms of radiation efficiency, power losses and scanning performance.…”

Mechanically Reconfigurable Linear Phased Array Antenna Based on Single-Block Waveguide Reflective Phase Shifters With Tuning Screws

This work presents the design and prototyping of a reconfigurable phased array in Ku band (16 to 18 GHz) implemented in waveguide technology. The design is based on the use of a novel seamless waveguide module integrating four reconfigurable phase shifters to adjust the relative phase shift between the unitary elements of a linear array, which are illuminated uniformly by a corporate waveguide feeding network. The phase shifters are implemented by a 90 ○ hybrid coupler in waveguide technology where two of its ports are loaded with a tunable reactive load, implemented in this proof of concept with a tuning screw. The four phase shifters have been manufactured in a single part using direct metal laser sintering, avoiding the losses related to bad electric contacts and misalignments associated to multipart devices. This also simplifies the assembly of the full phased array, leading to a modular approach with three parts whose design can be addressed separately. The experimental results for the complete array antenna show great performance and demonstrate that the main-lobe of the radiation pattern can be effectively scanned continuously between the angles −25 ○ and 25 ○ , with a high efficiency in the whole design band thanks to the proposed waveguide implementation.
