HF wheel rim antenna having several patch antennas
First Claim
1. A system for wireless data transmission, comprising:
- a plurality of stationary primary antennas; and
a plurality of secondary antennas situated on a rotating body;
wherein a first primary antenna transmits electrical energy to the secondary antennas, and a second primary antenna is provided for at least bi-directional communications for data exchange with the secondary antennas, and wherein the primary antennas are situated on a wheel housing of a vehicle, and wherein the main emitting direction of the primary antennas is towards the direction of a corresponding wheel in the wheel housing, and at an angle downwards relative to a horizontal plane of a road surface below the wheel.

Abstract
A system for wireless data transmission between a stationary transmitting/reception device and a rotating body, e.g., a vehicle wheel, having secondary antennas, is provided. A plurality of stationary primary antennas are coupled to the stationary transmitting/reception device, and a plurality of secondary antennas are positioned along a circumference of the rotating body. Amongst the plurality of primary antennas, at least one primary antenna is provided for transmitting electrical energy to the secondary antennas, and at least one other primary antenna is provided for communications with the secondary antennas. In this manner, data transmission independent of the speed of the rotating body and the position of the secondary antennas is achieved.
