Appliance for wireless data transmission between stationary transceiver and rotary body, e.g. car wheel tire, with numerous stationary primary aerials and numerous secondary aerials on wheel tire

摘要

Appliance for wireless data transmission between stationary transceiver (1,2) and rotary body (5), e.g. car wheel tire, comprises several primary aerials (1,2) and several secondary patch aerials (4) on car wheel tire. At least one primary aerial serves for transmission of electric energy to secondary aerials, and at least one serves for communication with secondary aerials. Preferably secondary aerials are fitted on support strip, typically wheel rim (6) fitted strip. Primary aerials may be fitted to wheel arch (8) of car (7).
