q A Wide-Beam Broadcasting Antenna Using a Curved Dipole on Reflector Plane

This paper presents a wide-beam antenna for broadcasting station by using a curved dipole antenna, which its both ends are electrically shorted on the surface of a square conducting reflector. The Method of Moment (MoM) is utilized to solve numerically the electrical currents that distribute along the curved dipole, which are used to determine the impedance characteristics and the radiation patterns of this antenna. The beamwidth of azimuth pattern of this antenna with shorted-end curved dipole on the reflector is around 120 degrees that is very suitable for TV broadcasting station. Having confirmed the validity of this approach, the UHF-band antenna prototype is fabricated, tested experimentally and shows good performance.
