A device with a substrate lens antenna uses a lens shaped dielectric body located on top of a planar feed antenna. A leaky wave antenna structure is used as feed antenna. The leaky wave antenna structure has a feed input and a first and second wave propagation branch extending from the feed input. The lens shaped dielectric body has a plane surface containing a focal point of the lens shaped dielectric body, the plane surface located adjacent the first plane, with the focal point adjacent the position of the feed input. Preferably the lens shaped dielectric body is spaced from the leaky wave structure at a sufficient distance to remove most of the propagation speed reduction effect of the dielectric on wave propagation along the leaky wave antenna. This helps to suppress undesirable side-lobes.

Composite Right/Left Handed (CRLH) Leaky-Wave Antennas (LWAs) are a class of radiating elements characterized by an electronically steerable radiation pattern. The design is comprised of a cascade of CRLH unit-cells populated with varactor diodes. By varying the voltage across the varactor diodes, the antenna can steer its directional beam from broadside to backward and forward end-fire directions. A CRLH Leaky-Wave Antenna for the 2.4 GHz Wi-Fi band is miniaturized by etching a Complementary Split-Ring Resonator (CSRR) underneath each CRLH unit-cell. As opposed to conventional LWA designs, the LWA layout does not require thin interdigital capacitors, significantly reducing the PCB manufacturing constraints required to achieve size reduction. The resulting antenna enables CRLH LWAs to be used not only for wireless access points, but also potentially for mobile devices. 1.

Doppler-nulling traveling-wave antenna relays for high-speed vehicular communications

Номер: US20150099459A1
Автор: Gary L. Duerksen
Принадлежит: EMPIRE TECHNOLOGY DEVELOPMENT LLC

An antenna relay system for facilitating wireless communication between mobile terminals on a high-speed rail vehicle and stationary base stations with substantially reduced Doppler shift effects comprises matched traveling wave directional antennas mounted to a high-speed rail vehicle and positioned collinearly alongside the railway. Both antennas continually transmit and receive at a fixed angle relative to the motion of the train so as to circumvent the Doppler shift. The signal transmitted or received by the stationary antenna is conducted to a nearest node for communication with an access network.
