Abstract
An antenna device includes a dielectric substrate, first and second antennas, and a parasitic coupler. The first antenna is formed on the dielectric substrate, and includes first and second radiating elements that extend in opposite directions. The parasitic coupler is formed on the dielectric substrate and is electromagnetically coupled to the first radiating element. The second antenna is formed on the dielectric substrate and is disposed proximate to the second radiating element.
Claims10
An antenna device, comprising:
- a dielectric substrate;
- a first antenna formed on said dielectric substrate, and including
- a first feeding element that has opposite ends,
- a feeding point that is disposed at one of said ends of said first feeding element, and
- first and second radiating elements that respectively extend from opposite sides of the other one of said ends of said first feeding element in opposite directions;
- a parasitic coupler formed on said dielectric substrate, disposed proximate to said first radiating element, and including a first grounding element, and a coupling element that extends from said first grounding element and that is electromagnetically coupled to said first radiating element;
- and
- a second antenna formed on said dielectric substrate, disposed proximate to said second radiating element, and including
- a second feeding element that has opposite ends,
- a second feeding point that is disposed at one of said ends of said second feeding element,
- third and fourth radiating elements that respectively extend from opposite sides of the other one of said ends of said second feeding element, and
- a second grounding element that extends from said second feeding element.
