We have theoretically studied the emission of a current line source surrounded by a cylindrical shell of left-handed material (LHM). We find the use of LHM shell greatly improves
the directional emission of the line source, forming a kind of LHM antenna. In a broadband frequency range, the radar cross-section of the antenna is lower than that of a parabolic reflector
antenna with the same aperture size, making it useful in stealth antenna design.
