With the demanding system requirements for the fifth-generation (5G) wireless
communications and the severe spectrum shortage at conventional cellular frequencies …

In order to fulfill the exponential increase in the demand of high-speed wireless links, future
XG wireless networks will be developed at higher carrier signal frequencies, reaching the …

A new configuration of a self-polarizing Fabry-Perot (FP) antenna is presented to generate
circular polarization with high gain levels using a simple linearly polarized feed. It consists of …

A leaky-wave slot array antenna fed by a dual offset Gregorian reflector system is realized by
pins in a parallel plate waveguide. The radiating part of the antenna is composed by parallel …

A multifed radially periodic two-dimensional leaky-wave antenna is proposed for the
generation of a directional beam continuously scanning in elevation by changing the …

Inspired by the checkerboard metasurfaces, we propose the design of low-RCS multi-beam
linearly polarized (LP) array antenna based on Pancharatnam-Berry (PB) phase. The …

Directive pencil beams scannable in both elevation and azimuth are obtained through a
planar phased array placed inside a Fabry-Perot cavity. The key element of the proposed …

New configurations of small-size shielded metallic Fabry–Perot (FP) antennas with improved
performance over a large frequency band are presented in S-band for space missions. The …

We describe here an optimization procedure to shape the radiation pattern of planar two-
dimensional (2-D) leaky-wave antennas. The structures under investigation are superstrate …

The next generation of space-based submillimeter-wave remote cometary mapping
instruments is being developed at NASA/JPL with two receiver bands at 210–240 GHz and …
