Special Issue Information

Dear Colleagues,

Antennas are a crucial component in wireless sensing and communication systems. In recent years, there have been significant advancements in antenna technology. One of the most important advances has been the development of small, low-profile antennas that can operate across a wide range of frequencies. These antennas are ideal for use in compact wireless devices such as smartphones, tablets, IoT, and wearable devices.

The use of smart antenna technology has also increased in recent years. Smart antennas can adapt their radiation pattern based on the location of the receiver, which can help to improve signal strength and reduce interference. Multiple input multiple output (MIMO) technology is another important development in antenna technology, which can improve data transfer rates and reduce errors.

In addition to these technologies, there are also ongoing research efforts to develop new antenna technologies for wireless sensing and communications. Some of them include the use of metamaterials, which are artificial materials that can manipulate electromagnetic waves in unique ways, and the use of terahertz radiation, which has the potential to revolutionize wireless communication due to its high bandwidth and ability to penetrate materials.

We believe that it is the right time to organize this Special Issue, and welcome any submissions related to antenna technologies for sensing and communications, such as: MIMO antennas; metamaterial antennas; AI for antenna designs; antenna measurements; et al. Hopefully, it will become an excellent reference source for people to learn the latest development in this important area.

The research on MEMS wireless sensing technology adapted to strong power frequency electromagnetic field environments is of great significance to our energy security, economic society, and even national security. Here, we propose a subwavelength cross-meandering resonator (0.49λ0 × 0.49λ0) to simultaneously achieve power frequency electromagnetic field shielding and wireless communication signal transmission. The element size of the resonator is only λ0/11, which is much smaller than that of previous works. In the resonator, a resonance mode with the significant near-field enhancement effect (about 180 times that at f = 1 GHz) is supported. Based on the self-made shielding box experimental setup, the measured shielding effectiveness of the resonator sample can reach more than 33 dB. Moreover, by integrating the cross-meandering resonator with the MEMS sensor, a wireless communication signal can be successfully transmitted. A dual-function cross-meandering resonator integrated with sensors may find potential applications in many military and civilian industries associated with strong power frequency electromagnetic fields.

This paper presents a compact wideband circularly polarized cross-dipole antenna with a low-pass filter response. It consists of two pairs of folded cross-dipole arms printed separately on both sides of the top substrate, and the two dipole arms on the same surface are connected by an annular phase-shifting delay line to generate circular polarization. A bent metal square ring and four small metal square rings around the cross-dipoles are employed to introduce new resonant frequencies, effectively extending the impedance and axial-ratio bandwidth. Four square patches printed on the middle substrate are connected to the ground plane by the vertical metal plates in order to reduce the antenna height. Thus, a compact wideband circularly polarized antenna is realized. In addition, a transmission zero can be introduced at the upper frequency stopband by the bent metal square rings, without using extra filter circuits. For verification, the proposed model is implemented and tested. The overall size of the model is 90mm×90mm×33mm (0.37λ0×0.37λ0×0.14λ0; λ0 denotes the center operating frequency). The measured impedance bandwidth and 3 dB axial-ratio (AR) bandwidth are 53.3% and 41%, respectively. An upper-band radiation suppression level greater than 15 dB is realized, indicating a good low-pass filter response. Full article
