Abstract
In accordance with one or more embodiments, a method includes receiving a first wireless signal via a feed point on an antenna body, wherein the antenna body includes a dielectric core having a first reflective surface and a second reflective surface that are spatially aligned in a reflecting telescope configuration; reflecting the first wireless signal via the first reflective surface and the second reflective surface to an aperture of the antenna body; and radiating the first wireless signal from the aperture.
Claims20
An antenna system, comprising:
- an antenna body including a dielectric core, the dielectric core having a first reflective surface and a second reflective surface;
- and
- a transmitting element that generates a wireless signal in response to a radio frequency (RF) signal;
- wherein the antenna body radiates the wireless signal through an aperture in response to receiving the wireless signal via an opening in the first reflective surface, wherein the wireless signal traverses the dielectric core and is reflected by the second reflective surface through the dielectric core to the first reflective surface and is reflected by the first reflective surface through the dielectric core to the aperture;
- wherein the transmitting element includes an antenna array that generates the wireless signal at a selected one of a plurality of transmitting element beam orientations including at least one off-axis orientation that is not coaxially aligned with a longitudinal axis of the antenna body;
- and
- wherein the generation of the wireless signal at the at least one off-axis orientation produces an off-axis antenna beam orientation of the wireless signal radiated via the aperture.
A method, comprising:
- receiving a first wireless signal via a feed point on an antenna body, wherein the first wireless signal is generated at a selected one of a plurality of transmitting element beam orientations including at least one off-axis orientation that is not coaxially aligned with a longitudinal axis of the antenna body, wherein the antenna body includes a dielectric core, the dielectric core having a first reflective surface and a second reflective surface that are spatially aligned in a reflecting telescope configuration;
- reflecting the first wireless signal via the first reflective surface and the second reflective surface to an aperture of the antenna body;
- and
- radiating the first wireless signal from the aperture, wherein the generation of the first wireless signal at the at least one off-axis orientation produces an off-axis antenna beam orientation of the first wireless signal radiated via the aperture.
An antenna structure, comprising:
- means for reflecting a wireless signal to an aperture of a dielectric antenna body, wherein the wireless signal is generated at a selected one of a plurality of transmitting element beam orientations including at least one off-axis orientation that is not coaxially aligned with a longitudinal axis of the dielectric antenna body, and wherein the means for reflecting is in accordance with a reflecting telescope configuration;
- and
- means for radiating the wireless signal via the aperture, wherein the generation of the wireless signal at the at least one off-axis orientation produces an off-axis antenna beam orientation of the wireless signal radiated via the aperture.
