Abstract
One or more anisotropic lenses, where the permittivity and/or permeability is directional, are used to vary one or more of beamwidth, beam direction, polarization, and other parameters for one or more antennas. Contemplated anisotropic lenses can include conductive or dielectric fibers or other particles. Lenses can be spherical, cylindrical or have other shapes depending on application, and can be rotated and/or positioned. Important applications include land and satellite communication, base station antennas.
Claims38
A communication system, comprising:
- a lens configured to be anisotropic with respect to dielectric permittivity;
- a radiating element mutually positionable with respect to the lens such that the radiating element can alternatively direct a first beam through the lens along a first orientation having a first dielectric permittivity, and a second beam through the lens along a second, different orientation having a different, second dielectric permittivity.
A communication system, comprising:
- a first lens mutually moveable with regards to a first element, between a first orientation and second orientation, wherein the lens has a first dielectric permittivity in the first orientation, and a second, different, dielectric permittivity in the second orientation;
- a first element positioned with the first orientation to produce a first output beam;
- a second lens mutually moveable with respect to a second element, between a third orientation and fourth orientation, wherein the lens has a third dielectric permittivity in the third orientation, and a fourth, different, dielectric permittivity in the fourth orientation;
- and
- a second element positioned with the third orientation to produce a second output beam.
A method of variably adjusting a characteristic of a first beam emitted by at least a first radiating element;
- comprising:
- installing an anisotropic lens in front of the first radiating element;
- and
- moving at least one of the lens and the antenna to adjust the characteristic.
