Abstract
Annular apparatus comprises a toroidal body composed of a material having high electromagnetic permeability and the body a through bore; an electrical device coupled to the toroidal body; and a loop antenna disposed to extend through the through bore in direct magnetic coupled relationship with the toroidal body. The loop antenna is in a mechanically de-coupled relationship with the toroidal body and lies substantially in a first plane that intersects the toroidal body opening at a right angle. In one embodiment, the electrical device comprises a transponder for monitoring cavity parameters in a pneumatic tire.

An apparatus comprising:
- a toroidal body composed of a material having high electromagnetic permeability and the body having a through bore,
- an electrical device coupled to the toroidal body,
- a loop antenna disposed to extend through the through bore in direct magnetic coupled relationship with the toroidal body.
An annular apparatus comprising:
- a toroidal body composed of a material having high electromagnetic permeability and the body having a through bore;
- a transponder coupled to the toroidal body;
- a loop antenna disposed to extend through the through bore in a magnetically coupled relationship and a mechanically de-coupled relationship with the toroidal body.
In an apparatus of the type comprising a toroidal body composed of material having high electromagnetic permeability and the body having a through bore;
- a transponder coupled to the toroidal body, and a loop antenna magnetically coupled to the transponder through the toroidal body, characterized in that the loop antenna extends through the central opening in a non-contacting and mechanically decoupled relationship with the toroidal body.
A method of associating a loop antenna with an electronic device through a toroidal body composed of a material of high elector-magnetic permeability and the body having a through bore, comprising the steps of:
- positioning the loop antenna to project through the through bore in non-contacting and mechanically decoupled relationship with the toroidal body,
- establishing a direct magnetic coupling between the loop antenna and the toroidal body, and coupling the electronic device to the antenna through the toroidal body.
A method of associating a loop antenna with an electronic device through a toroidal body composed of a material of high electromagnetic permeability and the body having a central opening, comprising the steps of:
- establishing a magnetic coupling between the loop antenna and the toroidal body;
- coupling the electronic device to the antenna through the toroidal body;
- embedding at least a portion of the antenna loop and at least a portion of the electronic device in an electrically non-conductive encapsulant material to maintain the antenna loop and the toroidal body in a specified orientation.
