Special Issue Information

Dear Colleagues,

We are inviting submissions to the Special Issue on Antenna Design and Application for 5G and Beyond.

Fifth-generation (5G) communication and beyond has attracted attention from both academia and industry, with many research outputs and significant improvements have been reported. Many reported efforts and research outputs with significant improvements in different aspects, such as data rate speed and resolution, mobility, latency, etc. In some countries, the commercialization of 5G communication is already established, as well as initial research of beyond technologies such as 6G.

MIMO antenna technology is a potential technique for meeting the needs of 5G/6G communications. It may considerably increase the system's capacity and withstand multipath fading, and it has become a focal point in wireless communications.

5G/6G devices are intended to support millimeter-wave (mmWave) and terahertz (THz) spectra in addition to sub-6 GHz frequency bands. Moving to higher bands, on the other hand, would present new issues and probably necessitate careful consideration of antenna design for smart devices. Compact antennas configured as conformal, planar, and linear arrays can be used to build phased arrays with high gain and directed radiation beams at various parts of base stations and user equipment.

A linear phased array antenna excited with a novel composite right/left-handed (CRLH) phase shifters structure is proposed. The phase of the conventional CRLH transmission line is controlled with magnetically aligned micron-sized particles embedded inside the unit cell of the CRLH transmission line. The cascading of unit cells produces the desired phase shifts for the main beam scanning of the linear antenna array operating at a 5.5 GHz center frequency for Wi-Fi 6 applications. The proposed phase shifter design has a very low insertion loss (0.5–2 dB), excellent matching characteristics with the antenna array (less than −10 dB) and a small phase error (1–2 degrees). A 1 × 4 linear patch antenna phased array operating at a 5.5 GHz center frequency of the Wi-Fi 6 band is simulated using the Method of Moments (MoM) simulator platform. Then, the array is driven with the proposed novel CRLH phase shifters for the main beam at broadside and the main beam steered at 15- and 30-degree scan angles toward the desired users. For experimental validation, multiple unit cells of the proposed phase shifters are fabricated, and the 1 × 4 patch antenna array is fed with these fabricated unit cells of the phase shifters. The phased array radiation patterns are measured using an in-house fully calibrated anechoic chamber and were compared with simulated phased array patterns. The measured phased array patterns are in good agreement with the simulated patterns. As compared with commercially available phase shifters, the proposed novel CRLH phase shifters do not need external complex biasing circuitry, which is a major advantage in space constraint limitations at the router side of multi-user MIMO-OFDM systems.
