The dual band dipole antenna array with corner reflector belongs to the category of reflector antenna arrays that are used in wireless telecommunication base stations, like the case of mobile telephony, and gives good and wide resonance in two frequency bands simultaneously, preserving in both two bands the same half power angular beam-width, the low secondary lobe level and the most possible maximum power gain, that are demanded according to any case. The dual band dipole antenna array with corner reflector consists of a mast (1) and two surfaces (2), that together compose the reflector, and an antenna array in front of the mast, situated on an axis parallel to the mast direction and composed of equidistant elements, which are orientated to array axis and fixed to the mast with the help of armrests (3). Each element consists of an active dipole (6) with dielectric cover (4), on whose surface a parasitic dipole (5) is adherent. The far-out active dipoles, in order to give better resonance, can have little larger length than the other active ones, which can be of the same length, and this construction technique is applied on parasitic dipoles as well.
