Special Issue Information

Dear Colleagues,

Millimeter-wave (mmWave) technology has emerged as a cornerstone for next-generation wireless communication systems, enabling ultra-high data rates, low latency, and massive connectivity. This Special Issue, titled "Millimeter-Wave Antenna Arrays: From Design to Applications", delves into the latest advancements, challenges, and innovations in mmWave antenna array technologies, spanning from theoretical design to practical implementations. With the rapid deployment of 5G and the ongoing development of 6G, mmWave antenna arrays play a pivotal role in achieving the desired performance metrics for future wireless networks. This issue brings together cutting-edge research on topics such as beamforming, massive MIMO, reconfigurable antennas, metamaterial-based designs, and integration with RF circuits. Additionally, it explores emerging applications in areas like autonomous vehicles, smart cities, IoT, and beyond. By bridging the gap between theoretical research and real-world applications, this Special Issue aims to provide a comprehensive resource for researchers, engineers, and industry professionals working at the forefront of mmWave technology. Contributions include original research articles, review papers, and case studies that highlight the transformative potential of mmWave antenna arrays in shaping the future of wireless communication.

This paper proposes two all-dielectric transmitarrays operating at Ka-band (26.5–40 GHz), achieving dual-polarization and beam-scanning functionalities. The dual-polarized design employs a cross-shaped dielectric post transmission unit, where the lengths of the two posts can be adjusted to enable independent phase modulation in the two orthogonal polarizations. Both polarizations provide 360° continuous phase coverage. To reduce the design complexity and achieve independent control of polarization, an optimized unit group with 16 states and 2-bit phase quantization is developed. A prototype of the all-dielectric transmitarray with 20 × 20 units is fabricated. The measured x/y-polarized peak gains are 25.3 dBi/25.5 dBi and the 1 dB bandwidths achieve 27% and 22%, respectively. To address feed–array integration, another all-dielectric transmitarray is further designed, which uses the same dual-polarized dielectric units, but replaces the horn feed with a dielectric rod antenna array. The feed array can generate multiple beams, enabling discrete beam-scanning within a 60° angle range. Both the dielectric transmitarray and the feed array can be fabricated by using 3D-printed technology, which greatly enhances the system integration and provides flexibility in generating multiple high-gain beams.
