Magnetically Scannable Leaky Wave Antenna
2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC), 2018This paper discusses the electronically scanning characteristics of a Leaky-Wave Antenna by means of controlling the real part of the leaky-mode complex longitudinal propagation constant at a fixed frequency. The structure is based on a standard rectangular waveguide section with a series of slots cut along its broad wall and loaded with a transversely-

Graphene terahertz leaky-wave antennas
2019In this chapter, we focus on the recent developments made in the context of graphene THz antennas, especially those exploiting the graphene field effect to reconfigure their radiating features. To this purpose, we first review the electronic properties of graphene in the THz range from both a physical and an engineering perspective.

Development of leaky-wave antennas
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016This presentation overviews the development of leaky-wave antennas (LWAs) and the area of leaky waves, starting with the first LWA that was introduced and the early pioneering work of Marcuvitz and Oliner in explaining leaky-wave theory. The development leads up through the present time, where LWAs have seen a renewed interest in the context of ...

The substrate integrated waveguide can easily be integrated with planar microwave circuits. Antennas designed on this transmission line have a planar structure, and can be fabricated by a standard PCB technology, so they are suitable for mass production.

Planar leaky-wave microstrip antenna
IEEE Antennas and Propagation Society International Symposium 1997. Digest, 2002In a single microstripline, the dominant mode is "quasi" TEM, which is a non-radiating surface mode. The higher-order modes, however, become leaky when the propagation constant is less than that of the free-space wave number, k/sub 0/. One of the simplest ways to realize a leaky-wave antenna is to use a regular microstripline properly excited by a ...

Metamaterial Based Leaky Wave Antenna
2019 8th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2019In this paper, a CRLH (Composite Right and Left Handed) leaky-wave antenna is proposed for V2X communication. The unit cell is composed of series chip capacitors and via for metamaterial properties. Also, the ground length is varied to attach on the automobiles. The size of the unit cell is 20×40 mm2 and the EM Simulation was used to see the results.

New millimeter-wave leaky-wave antennas
Proceedings of 1997 Asia-Pacific Microwave Conference, 2002This paper describes a variety of leaky-wave line sources derived from an open waveguide, on which modifications in the cross section are introduced to produce radiation. This allows the control of the leakage rate along the length of the radiator making it possible to shape the radiation pattern.

Compact SIW leaky wave antenna
2015 Third International Conference on Technological Advances in Electrical, Electronics and Computer Engineering (TAEECE), 2015A compact Substrate Integrated Waveguide (SIW) Leaky-Wave Antenna (LWA) is proposed. Internal vias are inserted in the SIW in order to have narrow walls, and so reducing the size of the SIW-LWA, the new structure is called Slow Wave — Substrate Integrated Waveguide — Leaky Wave Antenna (SW-SIW-LWA), since inserting the vias induce the SW effect.

Terahertz Fabry-Perot Cavity Leaky-wave Antennas
2019 PhotonIcs & Electromagnetics Research Symposium - Spring (PIERS-Spring), 2019In this work we examine the recent efforts made in the design of either efficient or reconfigurable Fabry-Perot cavity leaky-wave antennas (FPC-LWAs) in the terahertz (THz) range. We start by discussing the radiating performance of an FPC-LWA consisting of a grounded dielectric slab (GDS) covered with a periodic arrangement of fishnet-like unit cells ...
