Abstract
A mobile electronic device, such as a smart personal object includes an antenna system for emitting and receiving signals. The antenna system includes at least two antennas electrically connected in parallel to define an equivalent circuit having a reduced inductance with a substantially unaffected induced voltage for the equivalent circuit.
Claims20
A mobile electronic device comprising:
- a transceiver operative to transmit and receive signals within a frequency range,
- an antenna system coupled to the transceiver for emitting and receiving the signals, the antenna system including:
- a first antenna connected to the transceiver, the first antenna having a length, a width, and a number of turns, each turn having a direction of rotation,
- a second antenna connected to the transceiver and spaced apart from the first antenna, the second antenna having a length, a width, and a number of turns, each turn having a direction of rotation, the second antenna being electrically connected to the first antenna defining a parallel antenna circuit configuration, and
- a microprocessor coupled to the transceiver for processing the signals.
