Abstract

A communication device has at least one transmitter and/or receiver, an energy storage, and a signal coupling connecting the transmitter and/or receiver with the energy storage for transmitting and/or receiving a radio signal.

Claims

1. A communication device, comprising at least one element selected from the group consisting of a transmitter, a receiver, and both;

an energy storage;

a signal coupling connecting said at least one element with said energy storage for transmitting and/or receiving a radio signal.

2. A communication device as defined in claim 1, wherein said energy storage is formed as a member selected from the group consisting of a battery and an accumulator.

3. A communication device as defined in claim 2, wherein said battery or said accumulator has a first pole for said signal coupling.

4. A communication device as defined in claim 3, wherein said first pole is connected via an inductivity.

5. A communication device as defined in claim 3, wherein said battery or said accumulator has a second pole which is connected to ground.

6. A communication device as defined in claim 1, wherein said energy storage is an element of a magnetic loop antenna.

7. A communication device as defined in claim 1;

and further comprising a housing which accommodates said energy storage and said at least one element.

8. A detector, comprising a communication device including at least one element selected from the group consisting of a transmitter, a receiver, and both;

an energy storage;

a signal coupling connecting said at least one element with said energy storage for transmitting and/or receiving a radio signal.
