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 …

In this work, a broadband and broad-angle polarization-independent random coding
metasurface structure is proposed for radar cross section (RCS) reduction. An efficient …

A novel fixed-frequency electronically steerable Fabry-Pérot Antenna (FPA) with electronic
two-dimensional (2-D)(azimuth and elevation) steering capability is presented. The …

A simple model allowing us to predict beam steering characteristics in a Fabry-Perot (FP)
cavity antenna is presented in this letter. The structure consists of a ground plane and a …

A dual-polarized two-dimensional beam-steering Fabry-Pérot cavity antenna with a
reconfigurable partially reflecting surface (PRS) is proposed. A polarization-reconfigurable …

A high-gain low-profile Fabry-Perot (FP) leaky-wave antenna (LWA) presenting one-
dimensional high beam steering properties is proposed in this letter. The structure consists …

A compact ultrawideband (UWB) antenna based on a hexagonal split-ring resonator
(HSRR) is presented in this paper for sensing the pH factor. The modified HSRR is a new …

Transformation optics (TO) concept well known for its huge possibility in patterning the path
of electromagnetic waves is exploited to design a beam steering lens. The broadband …

We report the simulation, fabrication, and experimental characterization of a single-layer
broadband, polarization-insensitive and wide-angle near perfect metamaterial absorber …

A MEMS-tunable beam-shaping half phase-gradient (HPG) resonant cavity antenna (RCA)
is presented. Traditionally, the full phase-gradient (FPG) partially reflective surface (PRS) is …
