We present a true metasurface antenna based on electrically-small resonators. The resonators are placed on a flat surface and connected to one feed point using corporate feed. Unlike conventional array antennas where the distance between adjacent antennas is half wavelength to reduce mutual coupling be...
Figure 4. Architecture of the proposed metasurface antenna. (a) Diagram of the antenna elements is shown as exploded view, including the electrical ring resonators, Rogers TMM10I substrate as first substrate, ground plane (copper), Rogers RT5880LZ as second substrate, and the transmission ...
This paper presents the design and realization of a metasurface-based low-profile wideband Circularly Polarized (CP) patch antenna with high performance for Fifth-generation (5G) communication systems. The antenna consists of a modified patch, sandwiched between an array of 4 x 4 symmetrical square...
Here we report a programmable metasurface antenna that can approach the theoretical upper limit of the information mapping efficiency. Our approach combines non-recurrent encoding with spatial harmonic retrieval, and we show that the model maps most available programmable patterns to the first-harmonic ...
The metasurface is used as the ground plane of a Fabry-P茅rot cavity (FPC) antenna. The radiator of the FPC antenna is a dual-band patch antenna which has different polarizations in different bands, so by tuning the reflection phase of the metasurface correctly, the FPC antenna can work ...

We present a novel method to design a conventional Fabry–Perot (F-P) antenna but with low scattering. Combining a coding metasurface and an F-P antenna together could effectively reduce the scattering and keep high gain simultaneously. The coding element consists of two layers of square metallic...
Furthermore, this paper gives a key insight into the materials for a flexible antenna, the parameters considered for the design of a flexible antenna for 5G, the challenges for the design, and the implementation of a flexible antenna for 5G. Keywords: flexible antenna; sub-6 GHz; wireless ...
In this research article, a dual-polarized compact bow-tie-shaped irregular fractal antenna with a dual metasurface (DMS) for directional radiation applications is designed using a dual-mode simple feeding mechanism. A short-circuited strip linked betwee
