We present a new low-profile, wideband, transmitarray design based on polarization-
rotating (PR), miniaturized-element, frequency-selective surfaces (MEFSSs). These MEFSS …

Printed circuit metasurfaces have attracted significant attention in the microwave community
for their versatile wavefront manipulation capability. Despite their promising potential in …

Having studied the transmitarray antennas, it is found that the cells depending on their
location on the antenna aperture should have a specific slope in the transmission phase …

Radar systems are a type of sensor that detects radio signals reflected from objects located
a long distance from transmitters. For covering a longer range and a higher resolution in the …

As the physical size of a communication system for satellites or unmanned aerial vehicles
demands to be reduced, a compact antenna with high directivity is proposed as a core …

This research work presents the design and characterization of planar discrete lens
antennas (TA Transmit-Array antennas) based on a simple tri-layer elementary cell …

A new attractive elementary cell is proposed for 1-bit and 2-bit transmit-arrays in X-Band,
where the wideband and low loss characteristics are crucial. The proposed unit cell consists …

This paper presents a demonstration of a linearly-polarized transmit-arrays antenna with
highefficiency and wideband operating in X-band. The topology of the unit cell consists of …

This paper describes the design and demonstration of planar transmit-arrays operating in X-
band with 1-bit phase quantization and based on wideband high efficiency unit cells. The …

This paper presents an attractive unit cell for transmit-array antennas operating in X-Band
with linear and circular polarization. The presented unit cells consist of two identical patch …
