Special Issue Information

Dear Colleagues,

The rapid evolution of wireless communication technologies demands advanced solutions in propagation systems, antenna design, and microwave devices. This Special Issue focuses on cutting-edge research on next-generation wireless systems, including smart antennas, massive MIMO, metamaterial-based devices, and antenna, phased, and reconfigurable arrays. We invite contributions addressing theoretical innovations, experimental validations, and practical applications to overcome challenges in 5G/6G, IoT, and beyond.

This paper proposes a highly symmetrical miniaturized, frequency-selective surface (FSS) based on LC parallel resonance to optimize high-frequency passband characteristics, enhancing transmission efficiency under large-angle conditions. Through meandered design optimization, the device size is further reduced. Utilizing cell bending techniques and LC resonators, a single-layer FSS unit with parallel LC resonance is designed, achieving reflection and transmission peaks at approximately 1.56 GHz and 1.94 GHz, respectively. By employing co-planar and hetero-planar configurations to manipulate the effective capacitance through structural design, the reflection resonance frequency is effectively shifted beyond 0.7 GHz while preserving passband stability. The single-polarization characteristic is enhanced through cell arrangement. Experimental results validate the FSS’s transmission performance in the 1.71–2.2 GHz band under large-angle incidence (0–60°), with gain reduction not exceeding 1.2 dB. With a compact footprint (0.134λ × 0.134λ), a simple structure, and a stable angular response, the proposed FSS demonstrates strong potential for base station applications that require multi-band compatibility and spatial efficiency.
