Antennas for object identifiers in location systems
First Claim
1. An object identifier for identifying a location of an object in a location system, wherein the object identifier is attached to the object and radiates a signal including information on the location of the object, the object identifier comprising:
- a horizontal circuit board formed on a first plane for a circuitry of the object identifier, and a vertical loop antenna formed on a second plane, wherein the first plane is substantially perpendicular to the second plane.

Abstract
Transmitters or object identifiers are discloses that are able to radiate consistent power regardless of the object where the transmitters or object identifiers are placed. The transmitter or object identifier may include a vertical loop antenna. The loop plane of the vertical loop antenna is substantially perpendicular to the surface of the object where the transmitter or object identifier is placed. The transmitter or object identifier may include a folded vertical loop antenna where the loop plane of the vertical loop antenna is extended and folded to have additional loop planes. The antennas of the present invention enable the transmitter or object identifier to radiate consistent power regardless of the object where the transmitter or object identifier is placed and regardless of the orientation of the transmitter or object identifier.
