Claim Text:
1. An antenna comprising: a radiator; a ground plane spaced apart from the radiator; a substrate comprising a circuit formed as a conductive line extending on a top surface of the substrate, the circuit including one end and an opposite end each connected to the ground plane; a feeding pin for feeding an RF signal to the radiator, and the feeding pin being connected to the circuit; a first branch reactance disposed between the ends of the circuit, the first branch reactance including one end connected to the circuit and an opposite end connected to the ground plane; and a second branch reactance disposed between the ends of the circuit, the second branch reactance including one end connected to the circuit and an opposite end connected to the ground plane; a first stub disposed between the first branch reactance and the second branch reactance, forming a signal path of the antenna; a second stub disposed at one side of the second branch reactance, forming another signal path of the antenna; wherein a resonant frequency of the antenna is controlled according to at least one of a length and a width of the first stub and a length and a width of the second stub.
