Claim:
1. A planar inverted-F antenna comprising: a ground plane; a first radiator spaced apart from the ground plane and disposed to face and be opposite to a first surface of the ground plane; a feeding member connected to the first radiator for feeding a current to the first radiator; a shorting member formed by bending a portion of the ground plane and for shorting the ground plane and the first radiator to each other; and a second radiator formed by bending a portion of the first radiator and disposed to face and be opposite to the first surface of the ground plane and in parallel to the ground plane and disposed between the ground plane and the first radiator while being spaced apart from the ground plane and the first radiator and having a plate shape, wherein at least one of the first radiator or the second radiator is formed in a plate shape having a first slot for varying a frequency bandwidth characteristic of the antenna, wherein the second radiator is placed in a downward direction of the first radiator, and wherein the feeding member forms a coupling part for fixing a power supply part.
