Configurable omnidirectional antenna
First Claim
1. A configurable antenna, adapted to transmit or to receive electromagnetic radiation in a direction and over an angular width that are adjustable, said antenna comprising:
- an antenna that is omnidirectional about a given axis z, and said omnidirectional antenna comprising at least one biconical antenna; and
discrete reflector elements of controllable reflectivity passing through cones of the omnidirectional antenna without electrical contact and disposed on at least one circle centered on the given axis z, wherein said reflectivity of each discrete reflector element is controlled such that said configurable antenna transmits or reflects a multibeam distribution of said electromagnetic radiation.

Abstract
Configurable antenna, adapted to transmit or to receive at least one beam of electromagnetic radiation in a direction and over an angular width that are adjustable. The antenna includes an antenna that is omnidirectional about a given axis z. The omnidirectional antenna comprises at least one biconical antenna and the configurable antenna further comprises controllable reflectivity discrete reflector elements passing through the cones of the omnidirectional antenna without electrical contact and disposed on at least one circle centered on the given axis z. The antenna is applicable to mobile telephony.
