1. A peripheral antenna system, comprising:

  • communication circuitry located in an interior area of a circuit board, the communication circuitry configured to generate an RF signal into a feed line distribution point of the circuit board;

    a first antenna element located near a first periphery of the circuit board, the first antenna element configured to produce a first directional radiation pattern when coupled to the feed line distribution point; and

    a second antenna element located near a second periphery of the circuit board, the second antenna element configured to produce a second directional radiation pattern offset from the first directional radiation pattern when coupled to the feed line distribution point, wherein the first antenna element and the second antenna element substantially surround the communication circuitry and the first antenna and second antenna element collectively produce substantially omnidirectional and horizontally polarized radiation coverage that is substantially in the plane of the circuit board when the first antenna element and the second antenna element are coupled to the feed line distribution point.
