Resonant cavity antennas (RCAs) are suitable candidates to achieve high-directivity with a
low-cost and easy fabrication process. The stable functionality of the RCAs over different …

This research proposed an S-shaped metasurface (MTS)-based wideband circularly
polarized (CP) patch antenna for C-band uplink frequency spectrum. The proposed MTS …

In this communication, a new wideband resonant cavity antenna (RCA) with circular
polarization is proposed. A wideband circularly polarized (CP) crossed-dipole antenna acts …

The adaptation of dielectric windows as metamaterial superstrate over a bio-inspired Printed
Monopole Antenna (PMA) was evaluated in order to improve the detection sensitivity of Ultra …

In this letter, a multiple-beam antenna (MBA) scheme with reduced port dimension is
proposed for low-complex massive multiple-input-multiple-output (MIMO) systems. From …

Normally, the reported gain of the microstrip patch antenna is within 8 dBi. Using properly
located three shorting pins on three bisectors, the present work reports a method to convert …

This paper presents a high directive Fabry-Pérot (FP) cavity antenna by using highly
reflecting metasurface at 28 GHz for 5G applications. A highly reflecting metasurface is …

ABSTRACT A new type of metasurface (MTS) structure consisting of two diagonally
connected rings is proposed. Proposed MTS with 16-unit cells are arranged in 4× 4 cells …

The effect of using a non‐uniform reactive impedance surface (RIS) on the circular
polarisation performance of a planar antenna is investigated. It is shown that a very wide …

This paper proposes a novel triple‐layer partially reflecting surface (PRS) for designing a
highly directive antenna. The proposed PRS design has 54% improvement in impedance …
