Abstract
An antenna system includes a dielectric structure formed on a substrate; an antenna, partially within the dielectric structure, and supported by the dielectric structure; a reflective surface formed on the substrate. A shield blocks radiation from a portion of the antenna and from at least some of the dielectric structure. The shield is supported by the dielectric structure.
Claims18
An antenna system for detecting electromagnetic radiation, comprising:
- a dielectric structure;
- an antenna, partially within the dielectric structure, and supported by the dielectric structure, comprising:
- a first metal portion having a length lv;
- a filter portion comprising a portion of the dielectric structure adjacent the first metal portion on a first side of the filter portion and having a length ld which is a function of both lv and the dielectric constant of the dielectric structure, and
- a second metal portion on a distal side of the filter portion;
- and
- a detection system disposed to detect electrical field changes in the antenna.
