Abstract
An antenna system comprises first and second antennas that are arranged on a printed circuit board (PCB) and that include 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. Third and fourth antennas are arranged on the PCB and include an inner ring and an outer ring that is concentric to the inner ring.

An antenna system, comprising:
- first and second antennas that are arranged on a printed circuit board (PCB) and that include:
- an arc-shaped element having a concave side and a convex side;
- a conducting element that extends substantially radially from a center of said concave side;
- and
- a U-shaped element having a base portion with a center that communicates with said conducting element and two side portions that extend from ends of said base portion towards said concave side;
- and
- third and fourth antennas that are arranged on said PCB and that include an inner ring and an outer ring that is concentric to said inner ring.
A method, comprising:
- arranging an arc-shaped element of each of first and second antennas on a printed circuit board (PCB), wherein said arc-shaped element has a concave side and a convex side;
- extending a conducting element of each of said first and second antennas substantially radially from a center of said concave side of said arc-shaped element of each of said first and second antennas on said PCB, respectively;
- arranging a base portion of a U-shaped element of each of said first and second antennas on said PCB;
- communicating between a center of said base portion and said conducting element;
- extending two side portions of said U-shaped element from ends of said base portion towards said concave side on said PCB;
- and
- arranging an inner ring of each one third and fourth antennas concentrically with an outer ring of each of said third and fourth antennas on said PCB, respectively.
