“…As shown in [10], the use of functional materials like the barium-strontium-titanate (BST) allows to achieve higher operation frequencies than planar designs based on varactors like [4], [5]. However, since these designs are based on an experimental technology the achieved scanning range is lower than the one provided by other planar alternatives, while the power losses are relatively high (being indeed the highest of all the presented works).…”

“…In the last years different reconfiguration techniques have been developed in the area on antenna systems in order to increase their flexibility. The scanning of the radiation pattern main lobe, which is one of these techniques, has been extensively applied to planar array antennas by using tunable electronic components like varactor diodes, p-i-n diodes or digital phase shifters [1]- [5]. These components, which have been used by some of the authors in previous works [6], [7], allow a fast reconfiguration of the array characteristics but, as a counterpart, produce high levels of insertion losses.…”

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.

“…Introduction: Over the past decades, various phase shifters based on substrate integrated waveguide (SIW) have been implemented in different technologies such as liquid crystal (LC), ferrite low-temperature co-fired ceramic (LTCC) and varactor diodes as a tuning component to provide continues phase shift [1][2][3][4][5][6][7]. In [2] by partially replacing the dielectric substrate of SIW with LC and embedding an electric bias structure, an electronically tunable phase shifter is developed.…”

Continuously tunable 360° phase shifter based on planar waveguide technology for MM‐wave applications

et al. 2020

A continuously tunable phase shifter based on a substrate integrated waveguide (SIW) is proposed for high-performance applications at millimetre-wave frequencies. The proposed phase shifter consists of two slots cut on the SIW's broad wall and a high dielectric constant (HDC) slab over the slots. The phase shifting mechanism is based on perturbing the electric field of the SIW-slot by putting a HDC slab over two slots. The fabricated phase shifter exhibits linear phase-frequency response behaviour with an average insertion loss less than 2 dB over a phase shift range of 360°in the operating frequency band (29-31 GHz).

Pattern reconfigurable phased‐array antennas can implement the function of beam control and overcome the limited scanning angle of traditional phased‐array antennas without affecting the performance and operating frequency. In this article, a linear 1 × 4 phased‐array designed for wide‐angle scanning is presented. The unit includes an improved C‐type dipole antenna, an I‐typed resonator, and a ground. With the help of PIN diodes, the direction of the current on the patch is changed so that the unit can operate in two modes. The designed array has the advantages of a simple bias network, wide‐beam scanning coverage, high gain, and low‐sidelobe levels. Measurement results show that 2.85–3.66 GHz continuous beam scanning has been achieved in the range of −58° to 58°. Meanwhile, gain of up to 11 dBi is obtained, as well as in very good agreement with simulation. The results also verify the reconfigurability of the pattern and the feasibility of the design.
