Special Issue Information

Dear Colleagues,

As a key part of wireless communication systems, antenna performance can affect the connectivity of wireless communication. Therefore, novel approaches are needed to design more advanced antennas to adapt to the changing standards of wireless communication systems.

In order to meet the demands of increased data rates with low latency as well as wide coverage, 5G communication systems use both microwave and millimeter wave bands. Although some microwave and millimeter wave antenna design techniques, such as antenna miniaturization, array optimization, and bandwidth enhancement, have been extensively studied in the past,, due to the size and geometry of the antenna, this research is more limited in small devices. New microwave and millimeter wave antenna technologies need to be sought to meet the standards of future 5G and 6G communication systems.

This Special Issue will focus on the advanced research of antenna design for microwave and millimeter-wave sensing applications. Researchers are welcome to publish original research on the latest findings related to design methods of antennas such as (not an exhaustive list):

  • Antenna arrays and beamforming;
  • Millimeter-wave antennas;
  • Manufacturing error characterization;
  • Metasurface-based antennas;
  • On-chip antennas;
  • Antenna in package;
  • Antenna malnutrition;
  • Antenna optimization;
  • Body area networks;
  • Novel fabrication techniques.

A singly fed reconfigurable circular loop antenna is proposed for millimeter-wave (mmWave) communication systems. This antenna’s distinctive feature lies in its capacity to adjust both polarization and bandwidth characteristics, a capability made possible by the strategic integration of two PIN diodes. These diodes are engineered to function in various modes, allowing for three distinct polarization states and accommodating two distinct bandwidths. A meticulous alignment of these PIN diodes enables the utilization of a single DC bias network as a highly effective RF choke, which simplifies the design and reduces the associated losses. Additionally, a planar biasing network that consists of coplanar strip-lines (CPS) has been employed eliminating the need for lumped elements. The simple and totally planar configuration offers a choice of right-hand circularly polarized (RHCP) radiation or left-hand circularly polarized (LHCP) radiation at 28 GHz. This is accompanied by impedance matching and axial ratio (AR) bandwidths of 12.9% and 8%, respectively, over the same frequency range with a gain of 7.5 dBic. Moreover, when the PIN diodes are unbiased, the antenna offers linear polarization (LP) over two narrow bandwidths at 27 GHz and 29 GHz featuring a maximum gain of 7.2 dBic. Therefore, the proposed configuration offers three operating modes: wide-band RHCP, wide-band-LHCP, and LP over dual narrow bands. Significantly, simulated results closely align with the measured outcomes, affirming the robustness and accuracy of this design. Full article
