Kurzfassung englisch:
For the design of an antenna that will be directly attached to a car tire, the proximity effects due to the tire have to be considered. Measurements are performed on a dipole antenna that is mounted at the inside of the tire tread to determine the change in input impedance and resonant frequency caused by the dielectric rubber material and the metal reinforcement of the tire. A differential measurement setup with a vector network analyzer is presented to realize a symmetric antenna feed and to avoid a non-ideal balun. The measurement results are compared with simulations and good agreement is found.
