Abstract
An antenna has a main vertical planar part which is connected at its one end to the ground, and a main horizontal planar part which are both arranged in an L-shape. It has a secondary vertical linear part which is arranged in parallel with the main vertical planar part and connected at its one end to the feeding point. It also has a conductive secondary horizontal linear part which is connected between the main horizontal planar part and the secondary vertical linear part and is arranged in parallel with the main horizontal planar part, while being separated from the main horizontal planar part by a definite distance. This makes it possible to incorporate the antenna in the circuit board of wireless communication equipment, and the antenna is particularly suitable for miniaturizing the equipment.
