Horn Image Guide Leaky-Wave Antenna

MTT-S International Microwave Symposium Digest, 1981
A novel approach for designing a frequency-scanning millimeter-wave antenna is described. The antenna is constructed by using an image wide leaky-wave antenna embedded in a long trough with metal flares along both sides. The optimum flare angle for achieving maximum gain is theoretically predicted.

The printed leaky-wave array

2013 IX Internatioal Conference on Antenna Theory and Techniques, 2013
A leaky-wave antenna array is one of the attractive candidates for high efficiency and low cost planar antennas in centimeter- and millimeter-wave applications such as automotive radars and radio communication devices. In this paper, a planar leaky-wave antenna array composed of a printed periodic metal strip grating on a grounded dielectric waveguide ...

A leaky-wave groove antenna at optical frequency

Journal of Applied Physics, 2012
In the framework of nanoantennas functioning at optical frequencies, we present here a new kind of leaky-wave antenna realized as a groove in an aluminum superstrate, supported by a silver substrate. The antenna works in the optical frequency range where the silver acts as a dielectric with equivalent refractive index between zero and one.

Single-Conductor Strip Leaky-Wave Antenna

IEEE Transactions on Antennas and Propagation, 2003
The radiation characteristics of a single-conductor strip leaky-wave antenna is investigated. This structure has only a single-conductor strip on a substrate without a background plane. The broadband characteristics of the first higher order space-wave mode render this structure a broadband antenna. These result in a very wide leaky region.

The printed leaky-wave array

2014
A leaky-wave antenna array is one of the attractive candidates for high efficiency and low cost planar antennas in centimeter- and millimeter-wave applications such as auto-motive radars and radio communication devices. In this article, a planar leaky-wave antenna array composed of a printed periodic metal strip grating on a grounded dielectric ...

Leaky-wave antenna

The antenna has a layer arrangement (30) with three metallized layers (32, 34, 36) that are arranged parallel to each other and separated from each other by dielectric sheets (38, 40). Two of the layers comprise a two dimensions periodical metallization structure, and the third layer comprises a continuous metallization region. A stimulation structure (
