Problems solved by technology

[0011] However, this dipole-based structure of the antenna has the disadvantage of a rather irregular radiation pattern, especially with a drop-off in the dipole axis
Today, these latter implement dipole-type antennas for WiFi, which have the various drawbacks disclosed above, making these dipole-array-based antennas low-cost compared to clover or slanted-plane wheel-type antennas. effect

Embodiment Construction

[0047] An exemplary embodiment of the antenna of the present invention will now be described.

[0048] exist figure 1 In , an unmanned aerial vehicle 10 is illustrated, for example a fixed wing unmanned aerial vehicle such as the Disco from Parrot SA.

[0049] This UAV 10 comprises a fuselage 12, at the rear of which a propeller 14 is provided and in a lateral direction two wings 16 are provided, wherein in a "flying wing" type configuration these wings may be connected to the fuselage. 12 integrated together. The front camera 18 allows obtaining images of the scene towards which the drone is advancing.

[0050] The drone 10 is manipulated by a remote control device 20 equipped with a touch screen 22 that displays images captured by the camera 18 and various manipulation commands at the disposal of the user. The remote control device 20 is provided with means for a radio link with the drone, for example of the Wi-Fi (IEEE 802.11) local area network type, for communication f...

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 structureprinted 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.

Description

technical field [0001] The present invention relates to the remote manipulation of motorized equipment (hereinafter generally referred to as "drones"), and more precisely to the radio communication antennas used by these equipment for their remote manipulation. Background technique [0002] They are in particular flying drones, with rotary or fixed wings. However, the invention is not limited to the manipulation of and data exchange with flying equipment, and is also applicable to rolling equipment moving on the ground under the control of a remote operator, the term "drone" must be used in its most general sense come to understand. [0003] Typical examples of flying drones are the Bebop of Parrot SA in Paris, France (which is a rotary-wing drone of the quad-propeller helicopter type) or the Disco, also of Parrot SA (which is a fixed-wing drone of the flying-wing type). Another type of drone to which the invention is applicable is the Jumping Sumo, also from Parrot SA, wh...
