A wide band antenna has a ground plane, a dielectric member and a radiating patch. The dielectric member is mounted on the ground plane. The radiating patch is held by the dielectric member, is mounted on the ground plane and has a main conductor, a feeding conductor, a coupling conductor, an extension conductor and a shorting conductor. The main conductor has a first resonant mode. The extension conductor has a second resonant mode. The coupling conductor is capable of feeding high frequency signals into the main conductor and the extension conductor by capacitive coupling effect. With the main conductor, the extension conductor and the coupling conductor, the size of the wide band antenna is effectively reduced.
