Patent ID: 8519906

Claim:
An antenna comprising: a multilayered substrate including: a first layer disposed on an outer face of the multilayered substrate comprising a base portion and a spine portion extending from the base portion along a central axis of said multilayered substrate; a second layer disposed directly above or below said first layer configured as a first ground plane, the second layer comprising a base portion and a spine portion extending from the base portion along a central axis of said multilayered substrate; a third layer disposed directly above or below said second layer, the third layer comprising a first pole of a first driven element and a second pole of a second driven element disposed on a portion of said third layer and coupled to a first spine portion to form opposing poles of a first and a second antenna dipole; a fourth layer disposed directly above or below said third layer, the fourth layer comprising a second pole of a first driven element and a first pole of a second driven element disposed on a portion of said fourth layer and coupled to a second spine portion to form opposing poles of a first and second antenna dipole counterbalancing those on the third layer; a fifth layer disposed directly above or below said forth layer, the fifth layer configured as a second ground plane, wherein the second ground plane further comprises a base portion and a spine portion extending from the base portion along a central axis of said multilayered substrate; wherein said second and fifth layers are electrically coupled ground planes.
