1. An antenna comprising:
a dielectric substrate having a planar shape, said dielectric substrate comprising a first side and a second side;
an elongated feed disposed on the first side of the substrate, said elongated feed comprising a first longitudinally extending side and a second longitudinally extending side, said elongated feed comprising a first portion spaced apart from a second portion by a coupling component;
a ground plane disposed adjacent to and spaced apart from the feed on the first side of the substrate, wherein the ground plane comprises a first portion adjacent to and spaced apart from the first longitudinally extending side and a second portion adjacent to and spaced apart from the second longitudinally extending side;
a meander having a first end coupled to the elongated feed, said meander comprising a second end disposed opposite the first end, wherein the elongated feed and the meander are coaxial about a longitudinal axis, wherein the second end extends longitudinally, is coaxial with longitudinal axis and forms a common node;
a first extension extending from the second end adjacent to the meander at the common node, said first extension comprises a first lateral portion extending from the second end and a first longitudinal portion extending from the first lateral portion and disposed adjacent to the meander; and
a second extension extending from the second end adjacent to the meander at the common node, said second extension comprises a second lateral portion extending from the second end and a second longitudinal portion extending from the second lateral portion and disposed adjacent to the meander on an opposite side of the meander from the first longitudinal portion, wherein the first extension and the second extension are symmetrical about the longitudinal axis.
