| 1. An antenna, comprising:
a rectangular ground plane;
a rectangular conductor loop overlying the ground plane and having a side substantially aligned with an edge of the rectangular
ground plane; and
a monopole comprising a substantially linear conductor that extends substantially perpendicular to the edge of the ground
plane from a coupling point at a corner of the rectangular conductor loop at the edge of the ground plane,
wherein the conductor loop has dimensions of about 18 mm by about 8 mm, has a longer side thereof substantially aligned with
the edge of the ground plane, and is separated from the ground plane by a distance in a frequency range from about 5 mm to
about 10 mm; and
wherein the monopole has a length of about 36 mm.
