Abstract
Antenna structures and chiral radomes solve the aforementioned long-felt needs and provide efficient and multipolarized antenna structures and radomes. In a preferred embodiment, a radome for covering an antenna comprises a chiral medium. In a further preferred embodiment, a method of manufacturing an antenna structure comprising the step of embedding an antenna element in a radome which further comprises a chiral medium is also provided.
Claims7
An antenna structure comprising:
- at least one antenna element;
- a non-chiral dielectric substrate interfaced with the antenna element to hold the at least one antenna in a substantially fixed position in the antenna structure;
- and
- a radome further comprising a chiral medium interfaced with the at least one antenna element for covering the at least one antenna element.
1 more element
An antenna structure comprising:
- at least one antenna element;
- and
- a radome shell having a finite volume which comprises a chiral medium and a non-chiral portion wherein the at least one antenna element is embedded at least partly in the non-chiral portion of the radome shell.
