Ultra-wideband antenna with excellent design flexibility |
摘要 |
An ultra-wideband antenna includes a zone, an excitation means, and an adapting means. The zone is defined between first and second shaped surfaces such as to form a radiating element. The first and second shaped surfaces are also rotationally symmetrical in relation to a longitudinal axis of the antenna, and are disposed opposite one another in respect of a plane that is orthogonal to the longitudinal axis and that contains a horizontal axis. The first and second shaped surfaces are configured to control the characteristics of an electromagnetic field in the zone such that the antenna has an essentially-constant gain in the frequency band along an azimuth plane. The excitation means is configured to supply a signal in a localised manner in a central region of the zone. The adapting means is configured to promote a localised coupling between the excitation means and the zone.
