Abstract
A tag incorporated with a directional antenna. Directional antennas may utilize devices equipped with orientation-independent antennas to determine the location of radio frequency signals emitted by other objects. The system can exist in many different customizable configurations, sometimes utilizing orientation-independent antennas embedded in the tag.
Claims5
An item tracker comprising:
- a power source;
- an antenna structure comprising:
- a set of antenna elements, the elements including at least four radiating segments, with each segment generally facing in a selected one of four different orthogonal directions;
- at least two of the radiating segments providing a respective horizontal and vertical polarization;
- a selector module situated within the antenna structure, the selector module providing at least a horizontal and vertical polarization transmission line extending from corresponding horizontal and vertical polarization segments of the four sets of radiating elements;
- and
- a combining circuit connected to the transmission lines, to selectively enable a directional mode, omnidirectional mode, and polarization modes.
- the antenna configured to send one or more radio frequency (RF) transmissions in different selected directions;
- the item tracker configured to provide an alert condition when a receiving device receives a predetermined one or more RF transmissions.
