Therefore designing new compact antennas with good characteristics easy to manufacture and low cost applied for advance mobile terminals is quite necessary although number of similar studies had been conducted so far 1-4 . In this paper this antenna is chosen because it has advantages by its characteristics such as easier to design and manufacture than the PIFA antennas. Thank to simple structure and omnidirectional radiation monopole antennas have been found widespread applications in mobile communication systems. To meet the miniaturization of modern mobile communication equipments the design of compact monopole antennas is of particularly importance. In this paper a simple way has been proposed where a meandering conductor line printed on a dielectric substrate is used to reduce the size of a monopole antenna. But the resulted antenna was mainly applicable for single-band operation. To achieve dual-band operation in a compact monopole antenna design we propose a novel design of monopole antenna by extending conductor lines from rectangular meander monopole. The proposed antenna is fed by a
