Abstract
A radio frequency antenna for embedding within a conductive, dielectric material (such as tire rubber) is provided along with a method of embedding a radio frequency antenna in such a material. For very high frequency transmission, improved communication ranges are provided along with improvements in both antenna processing and tuning.
Claims25
A radio frequency device for integration with conductive, dielectric materials, said device comprising:
- a radio component for transmitting radio signals, receiving radio signals, or both;
- an antenna connected to said radio component;
- an adhesive coating substantially covering at least said antenna;
- and,
- an insulating layer attached to said antenna by said adhesive coating, said insulating layer being configured to insulate at least said antenna from the conductive, dielectric materials, said insulating layer having a relative dielectic constant less than the relative dielectric constant of the conductive, dielectric materials.
A tire having a radio frequency device integrated therein, said radio frequency device comprising:
- a radio component for transmitting radio signals, receiving radio signals, or both;
- an antenna connected to said radio component;
- an adhesive coating substantially covering at least said antenna;
- and,
- an insulating layer attached to said antenna by said adhesive coating, said insulating layer being configured to insulate at least said antenna from said tire, said insulating layer having a relative dielectic constant less than the relative dielectric constant of at least a portion of said tire proximate to said antenna when used with said tire.
A method for assembling a radio frequency device for use with a tire, comprising the steps of:
- providing a radio component for transmitting radio signals, receiving radio signals, or both;
- providing an antenna connected to said radio component;
- coating at least said antenna with an adhesive;
- and
- applying an insulating layer to said antenna for attachment by said adhesive coating, said insulating layer being configured to insulate at least said antenna from the tire, said insulating layer having a relative dielectic constant less than the relative dielectric constant of the tire.
