Antenna, in particular for an anti-theft system of a motor vehicle |
摘要 |
An antenna is constructed as an "on-board antenna" in the form of conductor tracks on a circuit board. A conductor track on the upper surface of the circuit board is electrically connected to a conductor track on the lower surface thereof through plated-through holes. This increases both the effective antenna surface area and thus the radiation power. |
