Abstract

In this letter, a dual-polarized dipole antenna with wide beamwidth in both E-plane and H-plane is developed. Compared to the typical printed dipole antenna, the radiator arms of the developed dipole antenna are bent into arc shapes to broaden the beamwidth. Moreover, four short arc-shaped metallic patches, which act as directors, are introduced to the outside of each radiator arm to further broaden the beamwidth. Simulated results show that the developed antenna achieves an operational bandwidth (where the value of reflection coefficients is less than −10 dB) of ~14.7% (1.76–2.04 GHz). In addition, the half-power beamwidths in both the E-plane and H-plane of the developed antenna are significantly broadened throughout the operating frequency band compared to the reference printed dipole. Specially, the beamwidths enhanced from 58° to 135° in the E-plane and from 95° to 128° in the H-plane, which validated the effectiveness of the developed beamwidth enhancement method. A prototype is fabricated and measured and shows good agreement with the simulated results.
