ABSTRACT:
An antenna system comprises a first antenna that is arranged on a printed circuit board (PCB) and that includes an arc-shaped element having a concave side and a convex side. A conducting element extends substantially radially from a center of the concave side. A U-shaped element has a base portion with a center that communicates with the conducting element and two side portions that extend from ends of the base portion towards the concave side. Second and third antennas are arranged on the PCB and include an inner ring and an outer ring that is concentric to the inner ring.
