Special Issue Information

Dear Colleagues,

Nowadays, wireless technology is growing faster than ever. This evolution is imposing a rising demand for the development of the area of antennas and propagation. Antennas are paramount components of wireless systems; hence, extensive research is required on antenna technology development. Although antennas play an imperative role in wireless systems, in most cases, they occupy considerable space in a system. Based on their application and other constraints, substantial consideration is required for antenna design, such as size, weight, cost, power and operating environment, structure, etc. As these devices are becoming more and more compact with additional functionality, antenna miniaturization, wideband, multiband and multibeam applications are gaining significant interest. State-of-the-art antenna technology can support the development of advanced wireless systems.

The focus of this Special Issue is to showcase the state-of-the-art progress in antennas and propagation areas. This Special Issue will cover innovative antenna technologies to support the development of advanced wireless systems, including, but not limited to, the following areas:

  • Planar antennas;
  • Antennas for handheld devices;
  • Beam-steering antennas;
  • High-gain antennas;
  • Reconfigurable antennas;
  • Antennas for 5G and beyond applications;
  • Conformal antennas;
  • Antennas and antenna array for RFID applications;
  • 3D-printed antennas;
  • Antenna miniaturization;
  • Multi-function antennas and arrays;
  • Antenna beamforming;
  • Flexible antennas.

This paper presents a novel dual-band antenna design for simultaneous 5G communication and localization services in high-speed train (HST) scenarios. It operates in the frequency range 1 (FR1) n78 band at 3.5 GHz and the FR2 n258 band at 26.2 GHz. The design combines a dielectric resonator antenna (DRA) and a planar patch antenna to achieve dual-band functionality. This provides efficient performance across both mid-band and millimeter-wave frequencies for advanced 5G applications. The dual-band configuration is motivated by the need to balance wide coverage and high data rates within a single, compact antenna design, addressing the specific challenges of maintaining stable connectivity and efficient spectrum utilization in high-speed, data-intensive environments. A common challenge in dual-band antenna designs is the interference between low- and high-frequency antennas, which can significantly degrade performance or even cause antenna failure. Our design addresses this issue by minimizing interference between the patch and DRA elements, ensuring stable operation across both frequency bands. As a result, the antenna achieves impressive gains and bandwidth, with a maximum gain of 6.8 dBi and an impedance bandwidth of 22.5% for the dual-band configuration. Also, both radiators present high total efficiency above 90%. The compact size of the antenna makes it highly suitable to be mounted on the roof of the train to enable 5G communication and location-based services for both safety-critical and liability-critical applications in HST scenarios.

The general objective of the work is to propose, examine, and study the innovations needed, providing a roadmap in order to place the next generation of wireless communication vision and concepts into technological reach. The main trends and directions are identified; relative challenges are addressed; and needed solutions are anticipated, proposed, and evaluated. In detail, to address the role of the antenna system in the wireless communication evolution, in the work at hand, we examine the challenges addressed by the increase in the degrees of freedom of the radiator systems. Specifically, we study the increase in the degrees of freedom provided by gMIMO, reconfigurable intelligence surfaces (RIS), holographic metasurfaces, and orbital angular momentum (OAM). Then, we thoroughly examine the impact that those potent technologies deliver to the mmWave, satellite, and THz wireless communications systems. Full article
