This paper presents a wideband angled dipole antenna and its array with a suppressed sidelobe levels. The paper will compare the effects of adding a perpendicular reflector to the antenna parameters. The proposed antenna consists of two angled dipoles of different lengths to broaden the bandwidth. The distance between the dipoles was adjusted to minimize the return loss between the two main resonance. The antenna array of four symmetrical angled dipole and perpendicular reflector and using nonuniform T-junction power divider was investigated. A useable bandwidth of 3GHz between 5 to 8 GHz was obtained from the four-elements array with a sidelobe level less than -28dB
