This paper presents dual band 4 ×4 Butler Matrix beam forming network integrated with antenna array operating at WLAN systems, 2.45GHz and 5.8GHz bands. Array antenna connected to a beam forming network can produce the desired multilobe radiation pattern. A signal fed in one port of Butler Matrix is divided into equal parts thus generate certain phase and equal amplitude which determine the beam direction. As a result, four orthogonal beams at -45°, -15°, 15° and 45° with high gain are produced. With the need for multi-functional and small-sized mobile telecommunication terminal devices, dual band terminals are widely spread, which are characterized by the simultaneous service of two or more frequencies in one device. In response to such demand, enhancement method of dual band beam forming network has been developed.
