A continuous beam-steering solution for circularly polarized (CP) radial-line slot array
(RLSA) antennas is presented and demonstrated with a fabricated prototype. The solution is …

This paper presents a near-field-focused (NFF) substrate-integrated waveguide (SIW)
antenna at a center frequency of 35 GHz with 2-D steerable focus. The proposed antenna is …

A resonant texture allows the impedance of a metal surface to be changed from an electric
conductor to a magnetic conductor, or any boundary condition in between. Varactor diodes …

We design and fabricate various sizes of 76-GHz post-wall waveguide-fed parallel-plate slot
arrays. The post-wall waveguide is an array of metalized via-holes with a narrow spacing in …

We present the synthesis of one-dimensional (line-source) leaky-wave antennas (LWAs) in
substrate integrated waveguide (SIW) technology with modulated geometry, demonstrating …

The paper discusses the possibility of generating a pseudo-Bessel beam, with a
propagation distance of several hundreds of wavelengths in microwave and millimeter …

A novel full-space scanning periodic phase-reversal leaky-wave antenna array is proposed,
designed in offset parallel stripline technology, and demonstrated experimentally. This …

A novel concept of planar printed-circuit microwave lens, based on the transformation of a
cylindrical surface wave into a modulated leaky wave, is presented in this paper. Inspired on …

Radial-line slot-array antennas (RLSAs) provide an extremely simple solution to achieve
high-gain circularly polarized radiation patterns without the need for complicated feeding …

This work proposes a dual-polarized planar antenna; two post-wall slotted waveguide arrays
with orthogonal 45/spl deg/linearly-polarized waves interdigitally share the aperture on a …
