Planar Leaky-Wave Antennas
Leaky-wave antennas use a traveling wave to radiate continuously along a radiating aperture in order to produce a focused beam of radiation. Planar leaky-wave antennas are particularly attractive since they use simple dielectric layers and/or metallic screens over a grounded substrate layer. A simple source such as a dipole or slot inside the substrate or on the ground plane excites the leaky w...
متن کاملDispersion Engineered Metamaterial-Based Conformal Leaky-Wave Antennas
In this paper, novel dispersion engineered conformal metamaterial-based leaky-wave antennas (LWA) based on composite right/left-handed (CRLH) concept are being reviewed. As a planar CRLH LWA is conformed on a curved surface, the radiation characteristics of LWA is distorted. The effect of conformation on a CRLH LWA is investigated. A dispersion engineering method is presented to compensate for ...
متن کاملContinuous leaky-wave scanning using periodically modulated spoof plasmonic waveguide
The plasmonic waveguide made of uniform corrugated metallic strip can support and guide spoof surface plasmon polaritons (SSPPs) with high confinements. Here, we propose periodically-modulated plasmonic waveguide composed of non-uniform corrugated metallic strip to convert SSPPs to radiating waves, in which the main beam of radiations can steer continuously as the frequency changes. To increase...
متن کاملCad of Coaxially End-fed Waveguide Phased-array Antennas
An alternative configuration for an infinite coaxially endfed waveguide phased-array antenna is explored. In the proposed configuration, the integration of the end-fed launcher and the output waveguide, rather than the waveguide in itself, acts as a basic radiator. This allows the design of more compact antenna elements. In order to analyze and optimize the structure, an accurate full-wave simu...
متن کاملGroove Gap Waveguide (GGW) H-plane Horn Antenna and a Method for Its Back lobe Suppression
recently a new structure called groove gap waveguide (GGW) is introduced to implement low loss microwave component devices especially for millimeter wave applications. This paper presents a new type of H-plane horn antenna making use of this new technology in which backward radiation is significantly suppressed by introducing a high impedance surface at the antenna aperture. The high impe...
