ABSTRACT:
This invention relates to a low-profile lens antenna. In particular, this invention relates to a low-profile lens antenna for use in a depression in a surface, e.g. a concavity in the ground. A low-profile lens antenna is provided that comprises a feed and a lens, wherein the lens is shaped to produce a radiation pattern that shows a general increase in power from 0° to 90° from the central axis of the antenna when illuminated with radiation from the feed.
