This article applies an in-house generalized ray-tracing (RT) model to efficiently compute
both the radiation pattern and the efficiency of geodesic lenses with nonrotationally …

The peniotron is a fast-wave vacuum tube that can generate coherent microwave radiation
in the millimeter-wave range. Although it uses a beam of gyrating electrons like other gyro …

Conformal antennas have been widely used in many fields due to their advantages of low
air resistance and better visual appearance. In this paper, an arced conformal leaky-wave …

In this contribution, the design of a novel logarithmic-spiral-shaped (LSS) anisotropic
dielectric polarizer is presented for millimeter-wave applications within the Ka-band (28–30 …

A novel frequency selective surface (FSS) architecture for dichroic mirrors is presented in
this work. The solution employs a full-metal unit cell, which was conceived as the …

A compact circularly polarized non-resonant slotted waveguide antenna array is proposed
with the aim of achieving wide-angle scanning, circular polarization, and low side-lobe …

The design of a wideband diplexer integrated with a 16‐slot Continuous Transverse Stub
(CTS) antenna array is presented. The diplexer‐antenna array module covers the whole …

We propose the use of a generalized ray-tracing model to design geodesic lens array
antennas. This model is capable of computing the radiation patterns and taking into account …

A compact, lightweight, and flexible array antenna for L-band applications is presented. The
antenna consists of a primary patch and two parasitic patches using corrugated copper …
