Patent ID: 6980155

Claim:
An internal diversity antenna, comprising: a common ground element formed as a conductor having predetermined length for grounding the antenna; a first radiating element for radiating a vertically polarized wave of a predetermined band according to a ground condition of the antenna, wherein one end of the first radiating element is perpendicularly connected to one end of the common ground element and the other end of the first radiating element is open; a first feeding element connected to the first radiating element for feeding electric current to the first radiating element; a second radiating element for radiating a horizontally polarized wave of the predetermined band according to the ground condition of the antenna, wherein one end of the second radiating element is perpendicularly connected to the other end of the common ground element and the other end of the second radiating element is open; and a second feeding element connected to the second radiating element for feeding electric current to the second radiating element.
