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 article presents an aperture-shared dual-band large frequency-ratio high gain antenna
for sub-6 GHz and millimeter-wave (mm-wave) bands applications. Initially, the partially …

Wideband differentially fed patch antennas under dual high-order modes for stable high
gain are proposed in this communication. The working principle is verified on a differentially …

A dual circularly polarized (CP) Fabry-Perot (FP) resonator antenna is presented in this
paper. A linear to circular polarization conversion metasurface (MS) is employed as the …

A novel hybrid reflection method is proposed to realize wideband gain enhancement and
radar cross section (RCS) reduction properties for Fabry-Perot (FP) antennas. This method …

A substrate integrated differential cavity-backed dual-polarized dielectric resonator antenna
with a wide bandwidth, low profile, high isolation, and improved gain is presented. The …

A transmitting lens antenna with focused beams by employing four-layer phase-gradient
metasurface (PGMS) is proposed. A wideband slot-coupled antenna is mounted close to the …

This work introduces a new design of a Fabry–Perot cavity (FPC) antenna with great filtering
response based on a novel filtering feeding scheme. Unlike the traditional method of …

A novel dual-polarized antenna with very low profile using nonuniform metasurface is
presented in this letter. The proposed antenna is composed of two dipoles placed crosswise …

We propose the design and testing of a 2-D Fabry-Perot structure based on a multilayer (ML)
slab arrangement fed by a circular array of simple sources. Such a class of planar leaky …
