Abstract: An antenna includes a piezoelectric disc. The antenna further includes a first electrode disposed on a first surface of the piezoelectric disc and a second electrode disposed on a second surface of the piezoelectric disc that is opposite to the first surface. The first electrode and the second electrode are to receive a time-varying voltage to excite a mechanical vibration in the piezoelectric disc, and the piezoelectric disc is to radiate electromagnetic energy at a particular frequency responsive to the mechanical vibration.

Abstract: This invention concerns a multibeam antenna with adjustable pointing, comprising a single reflection arrangement and a plurality of radiating sources arranged opposite the reflection arrangement and suited to emit and/or receive radiofrequency (RF) signals, the reflection arrangement defining a centre, a focal plane, and a focal point located on the focal plane.
The antenna is characterised in that at least one of the radiating sources (‘mobile source’) is movable substantially independently of the or each other radiating source on a scanning surface to adjust the pointing of the antenna, wherein the scanning surface coincides with the focal plane or is tangential to it at the focal point.
