Definitions
- Transmitting device for a plurality of mutually parallel, independently of each other via a respective supply cable antennas
- the invention relates to a transmitting device for a plurality of mutually parallel antennas, which can be supplied independently via one feed line each.
- switching means are used in series in the supply lines of the antennas for such transmission devices and thus released the flow of current to each antenna to be controlled, as can be seen, for example, the WO 2004/001681.
- the switching means is arranged on the low side to the ground potential. Although the circuits are interrupted to the inactive antennas, but the transmission voltage of the transmission frequency over the supply line is present.
- a high-side switch between excitation circuit and antenna has no ground reference and is therefore difficult semiconductors feasible.
- DE 100 04 616 A1 has a relay circuit for short-circuiting the inactive antennas, which likewise can not be implemented by semiconductor technology without further ado.
- the object of the invention is therefore to present an alternative transmitting device, which is easy to implement and also has no couplings.
- the basic idea is to bridge the inactive antennas by a parallel controllable switching means towards ground.
- the individual leads each have capacitors for decoupling, which are to be considered in the calculation of the frequency of the bandpass and therefore in their entirety can form the capacitive component of the bandpass completely, so that no further capacitor is required.
- Fig. 1 circuit diagram of an access control system with 5 transmitting antennas The example shows 5 transmission antennas of an access control system in a motor vehicle, for example a so-called keyless entry system for keyless opening and closing of the central locking in dependence on the presence of a transponder.
- the multiplexer transistor T1 is switched off (high impedance), all remaining transmit antennas (_2, _3, _4, and _5) are switched off, in which the multiplexer transistors T2, T3, T4, T5 are switched on (low resistance) ) are. Thus, no transmission signals at the output of the switched-off antenna or its supply more.
- the transmit antenna is tuned to resonance via C1 C_ant_1.
- the resonant frequency of the first bandpass is:
- this antenna multiplexer is that no signal voltage is present at the supply line of the switched-off antenna, in contrast to the realization "current-switch multiplexer", where only the circuits are interrupted and thus the transmission voltage of the transmission frequency is present via the supply line.
- these switching means can be implemented and controlled simply semiconductor technology.
