Meta-Wall Integrted Substrate Antenna for Millimeter-Wave Application

A wideband substrate meta-antenna fitting into the technology of printed circuit boards is presented at millimeter wave. In this design, A novel approach for designing antennas based on meta-wall is proposed for the first time, which is a completely integrated structure. Unlike the classical independent structure, we resolve multiple radiation modes within an entire structure by designing both dielectric and metallic metasurface. The intentional radiation modes can be bound in a fixed part, leading to the similar radiation performance as dielectric resonator antenna. We believe that this design further integrates the design of antenna and metasurface and can provide a reference for future device. The simulated results show that the proposed antenna can form an array easily with wideband and low-profile, which can also provide basic beam scanning characteristics. © 2024 IEEE.
