A printed dipole antenna with reflector features a high gain. Accordingly a dual-polarized reflector antenna with high gain for base transceiver stations (BTS) is proposed. Design of this antenna is based on λ/2 printed dipoles supplied through Γ-shaped microstrip feed lines. The basic structure of the antenna is composed of two orthogonal radiating elements which are separately printed on two substrates. Each element has a λ/2 printed dipole on one side of the substrate and a 50 Ω Γ-shaped microstrip feed line on the other side. The combination of these two orthogonal radiating elements provides proper ± 45̂ dual-polarized characteristics for BTS applications. The radiating elements are placed on an aluminum slot reflector with side walls in order to make the antenna directional, and to increase the gain and the fron to back ratio (FBR) as well. A prototype of this antenna is manufactured and it covers the frequency range of 1.4–2.6 GHz due to the measured results. The average measured gain and half-power beamwidth (HPBW) are obtained 8.35 ± 0.55 dBi and 165̂, respectively.
