Special Issue Information

Dear Colleagues,

With the complex electromagnetic environment and increasing demand on communication capacity, some different technologies have been proposed and studied to fulfill the severe requirements. Among them, the massive MIMO antenna array is a promising technology to increase the channel capacity by leveraging multiple antenna elements to receive and transmit electromagnetic waves. On the other hand, massive MIMO antenna arrays can further adapt to the time-varying environment at millimeter-wave bands via beamforming. Very recently, metasurfaces and reconfigurable intelligent surfaces have been extensively studied as promising and exciting technologies for the evolved 5G and upcoming 6G wireless communications. Metasurfaces and reconfigurable intelligent surfaces comprise a plethora of subwavelength unit cells. The behavior of the unit cell (e.g., phase, polarization, and amplitude) can be flexibly controlled. As a result, metasurfaces and reconfigurable intelligent surfaces can manipulate the performance of electromagnetic waves impinging on them, converting the unfavorable electromagnetic environment to a favorable one for high-quality and high-efficiency sensing, location, and wireless communications.

This Special Issue is being launched with the aim of collecting recent research on advanced massive MIMO antenna arrays, metasurfaces and reconfigurable intelligent surfaces for sensing, location, and wireless communications.

Authors are kindly invited to submit their contributions to this Special Issue on topics including, but not limited to, the following:

  • Innovative theories and approaches for large communication capacity;
  • Massive MIMO antenna arrays;
  • Metasurfaces;
  • Reconfigurable intelligent surfaces;
  • Smart environment;
  • Beamforming technology;
  • New theories and algorithms for accurate sensing and location;
  • New applications of materials and new materials for wave manipulation

In satellite remote sensing (SRS), there is a demand for large-power microwave components. A Butler matrix is essential to a transmitting antenna array in SRS. This article illustrates the electrical and mechanical design, simulation, and test results of a large-power planar beamforming network for SRS at C-band. It is a 4 × 4 Butler matrix based on square coaxial lines. Short-ended stubs are used in the Butler matrix to broaden its bandwidth by 10%, support inner conductors, and enhance heat transfer in vacuum environments. The simulation results are consistent with the measured results. The reflection coefficient is less than −18 dB, and the isolation is more than 23 dB from 3.8 GHz to 4.2 GHz. The insertion losses are less than 0.6 dB, and the phase errors are better than ±6°. The measured peak microwave power of the proposed Butler matrix is 9 kW. Its size is 440 × 400 × 40 mm3. The proposed Butler matrix beamforming network can be applied to SRS systems. Full article

This article proposes a dual-band, frequency- and polarization-selective surface. Multiple resonant modes are introduced using the U-shaped resonator with a ground via to achieve dual-band responses and polarization selectivity. Two symmetrically grounded U-shaped resonators are coupled through electrically coupled apertures in a common ground, resulting in a passband with two transmission zeros per polarization. A general design flowchart and additional examples at the S, X, and K-bands are presented as well. A prototype at X-band is analyzed, fabricated, and measured, showing the passband center frequencies of 9.68 GHz and 10.73 GHz, factional bandwidths of 3.45% and 3.48%, and insertion losses of 0.9 dB and 1.1 dB, respectively. Due to the high selectivity, small frequency ratio, low profile, and stable performance under oblique incidence, the proposed designs have application potential in wireless communication systems.

A non-resonant metasurface (NRMS) concept is reported in this paper to improve the isolation of dual-polarized and wideband large-scale antenna arrays. By properly designing the NRMS, it can perform stable negative permeability and positive permittivity along the tangential direction of the NRMS within a wide band, which can be fully employed to suppress the mutual couplings of large-scale antenna arrays. At the same time, the proposed NRMS can also result in positive permittivity and permeability along the normal direction of the NRMS, which guarantees the free propagation of electromagnetic waves from antenna arrays along the normal direction. For demonstration, a 4×4 dual-polarized antenna array loading with the proposed NRMS is designed to improve the isolations of the antenna array. The simulations demonstrate that the isolations among all ports are over 24 dB from 4.36 to 4.94 GHz, which are experimentally verified by the measured results. Moreover, the radiation patterns of antenna elements are still maintained after leveraging the proposed NRMS. Due to the simple structure of the proposed NRMS, it is very promising to be widely employed for massive MIMO antenna arrays. Full article
