Special Issue Information

Dear Colleagues,

With the increasing demand for wireless communication and intelligent sense in recent years, there has been a need to develop novel antennas that are flexible, reconfigurable, and can conform to various shapes and surfaces. These novel antennas can be used in a variety of applications, including wearable devices, IoT sensors, and medical devices.

This Special Issue aims to provide a comprehensive platform for researchers, engineers, and practitioners to share their insights, discoveries, and advancements in antenna design, wireless communication systems, and intelligent sensing technologies. It covers a broad range of topics related to antenna technologies, including, but not limited to, the following:

  • Advanced antenna designs for wireless communication systems, including 5G and beyond.
  • Miniaturized and low-profile antennas for compact and wearable devices.
  • Wideband and multiband antenna designs for enhanced communication capacity.
  • MIMO antenna systems for improved data rates and link reliability.
  • Smart and reconfigurable antennas for adaptive wireless communication.
  • Antennas for Internet of Things (IoT) applications and wireless sensor networks.
  • Millimeter-wave and terahertz antennas for high-speed wireless communication.
  • Antenna integration in intelligent sensing systems for applications such as radar, imaging, remote sensing and biomedicine.

Abstract
Rigid-reflector spaceborne antennas (RRSAs) are well-suited for high-frequency application scenarios due to their high surface accuracy. However, the low stowing efficiency of RRSAs limits the aperture diameters and further deteriorates the electromagnetic (EM) performances in terms of gain, resolution and sensitivity.

Rigid-reflector spaceborne antennas (RRSAs) are well-suited for high-frequency application scenarios due to their high surface accuracy. However, the low stowing efficiency of RRSAs limits the aperture diameters and further deteriorates the electromagnetic (EM) performances in terms of gain, resolution and sensitivity. After conducting systematic feature analysis with respect to several typical RRSAs, we propose a novel type of RRSA to solve the aforementioned problems. Inspired by the pose adjustment process for a higher stowing efficiency of traditional RRSAs, we also propose a new segmentation scheme of a reflective surface consisting of a deviation-angle panel that facilitates a higher stowing efficiency. Based on this scheme, its corresponding folded configuration is implemented by combining Euler’s rotation theorem and the idea of parameter identification. In addition, we also compare the stowing efficiency of different schemes to verify the high stowing efficiency of the configuration. Finally, we perform mechanism/structure design and deployment dynamics to demonstrate that the antenna can be successfully deployed and exhibits excellent deployment quality. The results suggest that the proposed antenna possesses higher stowing efficiency than that of the same kind, with a stable deployment and interference-free process. Full article

In this letter, a dual-polarized metal Vivaldi phased array antenna composed of independent structural elements is proposed, covering 6–18 GHz. By designing Vivaldi elements with a flexible and complementary structure, arrays of arbitrary shapes and scales can be constructed. The resonance caused by structural discontinuity is critically studied and eliminated to ensure good performance across the entire band. The antenna elements are fed by 50-Ohm SSMP connectors and manufactured from 2A12 aluminum alloy. An array prototype consisting of 8 × 8 dual-polarized metal has been fabricated and tested with active transmit/receive (T/R) modules to demonstrate the design concept. The array exhibits excellent beam-scanning characteristics in both the E-plane and H-plane, within the scanning range without grating lobes, which shows good agreement with the simulated results. The measured gain results are within the range of 15.2 to 24.8 dBi, and the aperture efficiencies are greater than 91% in the entire operating band. The wideband antenna technology involved in this study can effectively help increase the capacity of communication systems and meets the intentions of the Special Issue. Full article
