Abstract
An antenna includes one or more elementary antennas with non-coplanar planar loops extending about a main axis in respective inclined planes. Each elementary antenna is formed by tracks of a structure printed on a circuit support extending in the inclined plane, with two imbricated planar loops tuned on frequencies includes in two respective distinct WiFi frequency bands. With a flexible circuit support, an antenna housing of the drone includes a conformed hollow cavity comprising a plurality of inclined planar faces, which are the counterparts of the inclined planes of the elementary antennas, against which bear these latter after deformation of the flexible support.
Claims18
An antenna with a near-spherical radiation pattern, said antenna being an antenna of the clover-leaf or skew-planar wheel type, comprising:
- a plurality of elementary antennas with non-coplanar planar loops extending circumferentially and symmetrically about a main axis of the antenna and remote from this axis, in respective planes inclined with respect to the main axis, these inclined planes forming an angle with respect to a radial plane;
- and
- a module for the coupling and the adaptation of the elementary antennas to a coaxial cable for the power supply of the antenna,
- wherein each elementary antenna is formed by tracks of a structure printed on a circuit support extending in said respective inclined plane;
- and
- each elementary antenna comprises two imbricated planar loops, tuned on frequencies comprised in two respective distinct WiFi frequency bands.
A drone comprising:
- a drone body from which extend laterally two wings and at least two arms;
- at least one antenna comprising a plurality of elementary antennas with non-coplanar planar loops extending circumferentially and symmetrically about a main axis of the at least one antenna and remote from this axis, in respective planes inclined with respect to the main axis, these inclined planes forming an angle with respect to a radial plane and a module for the coupling and the adaptation of the elementary antennas to a coaxial cable for the power supply of the at least one antenna, wherein each elementary antenna is formed by tracks of a structure printed on a circuit support extending in said respective inclined plane and each elementary antenna comprises two imbricated planar loops, tuned on frequencies comprised in two respective distinct WiFi frequency bands;
- and
- at least one antenna housing, receiving said antenna.
