Abstract:
1. 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 clement 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, spaced apart from said parasitic coupler in a first direction, 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 clement that extends from said second feeding element, wherein: said first antenna is disposed between said parasitic coupler and said second antenna, said first radiating element extends in the first direction away from said second antenna, and said second radiating clement extends in the first direction away from said parasitic coupler.
