We propose the design and testing of a 2-D Fabry-Perot structure based on a multilayer (ML)
slab arrangement fed by a circular array of simple sources. Such a class of planar leaky …

A millimeter-wave near-field-focused (NFF) full 2-D frequency-scanning antenna array is
presented in this article. The proposed antenna is achieved by combining an NFF ridged …

A millimeter-wave self-progressive near-field focusing (NFF) 2-D full frequency scanning
ridge-gap waveguide slot array antenna is proposed in this article. In the proposed array …

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 …

In this paper, a wide-angle frequency-scanning array antenna is presented for three-
dimensional (3D) radar. Initially, a modified composite right/left-handed (CRLH) unit cell …

A compact and cost-effective antenna array that enables a 2-D full 90° cone-metric-space
beam-scanning is designed in this article. To achieve this unique function, a resonant-type …

In this work, the authors experimentally show Dirac Leaky Wave Antennas (DLWAs) at upper
microwave frequencies. For the first time, DLWAs are implemented using simple Parallel …

A periodic microstrip leaky wave antenna (MLWA) constructed of non-uniform aspect ratios
microstrip patch periods is presented in this communication. Effective equations and …

In the present paper, the parameters of the composite right/left-handed transmission lines
antennas (CRLH TL) are optimized by a good mathematical approach, based on a periodic …

In this paper, a new approach is proposed to improve the radiation efficiency of a frequency
beam-scanning antenna. In this proposed approach, the entire antenna is divided into two …
