CMA-Guided Co-Design of Antenna and Metasurface for Dual-Circular Polarization at Millimeter Wave
This paper presents a higher order mode (HOM)-based dual circularly polarized antenna design for millimeter wave applications. The main radiating element is a SIW cavity-backed antenna with curved slots, and a 4 × 4 array of square patches, is utilized as a metasurface to enhance the overall antenna performance. Charac...

Multifunctional tunable terahertz metasurface with 20 independent channels and ultra-low crosstalk via bidirectional full-polarization decoupling and frequency multiplexing
Boosting channel density represents a core demand for terahertz (THz) metasurfaces deployed in next-generation information processing systems. However, the dense integration of multiple functions often leads to severe inter-channel crosstalk, which remains a critical bottleneck in this field. Here, we design a compact...

Concurrent electromagnetic signature reduction and isolation improvement in a metasurface-integrated graphene-dielectric resonator MIMO tunable antenna for THz communication systems.
The design of a dual-port antenna with decreased RCS and circular polarization is presented in this study. A cylindrical silicon dielectric resonator is excited via an asymmetrical plus-shaped aperture-coupling device to produce circularly polarized radiation (3.45-3.85 THz). An EBG metasurface integrated on the unders...

Millimeter-Wave Antenna with Integrated Phase-Controlled Metasurface for Adaptive B5G Applications
A millimeter-wave antenna design with an integrated phase-controlled metasurface for advanced B5G adaptive wireless communication systems is presented. The antenna system combines a planar antenna array of 32 patch antennas with an active metasurface based on microresonators with embedded varicaps, which provides a hig...

Single-Layer Large Frequency-Ratio Dual-Band Vivaldi-Leaky-Wave Embedded Antenna for Coverage Enhancement
In this letter, a single-layer shared-aperture Vivaldi-leaky-wave embedded antenna (V-LWEA) for coverage enhancement is presented. To mitigate the open-stopband effect and increase leakage rate in high-band (HB), periodic elliptical-slot unit cells are introduced, which facilitate single-port excitation without bulky a...

Quasi-Bound State in the Continuum-Driven Co-Frequency Polarization-Multiplexed Tunable Terahertz All Dielectric Metasurface
Quasi-bound states in the continuum (q-BICs) provide an effective approach for achieving strongly confined resonances in metasurfaces. However, the simultaneous realization of high-Q, polarization-multiplexed, and tunable resonances at a single frequency using a single resonant meta-atom remains challenging. Here, we n...
