Abstract

In this letter, a wideband dual-polarized dipole antenna is proposed for base station applications. By bending the arms of the dipole, the radiator size is reduced. Meanwhile, a new resonant mode occurs at high frequency. Besides, four shorting stubs are employed to improve the impedance matching. Finally, a wide operating bandwidth is realized by combining all resonant modes. A prototype of the proposed antenna is fabricated and tested. Experimental results show that the antenna has a wide impedance bandwidth of 53% (1.65-2.84 GHz) for VSWR<1.5 at two ports and a high port isolation of 26 dB. Also, a stable antenna gain around 7.9±0.5 dBi and a stable radiation pattern with 3-dB beamwidth of 67.5°±3.5° are obtained within the entire band of operation.
