Abstract

A wideband and widebeam magneto-electric (ME) dipole antenna is designed in this paper. Based on the conventional magneto-electric dipole antenna, a bent vertical metal plate is added to the electric dipole, and the impedance bandwidth (IBW) and beamwidth of the antenna are widened together. Inclined metal walls are added on both sides of the metal ground to improve the gain at high frequency and make the antenna gain more steady in the operating bandwidth. To further broaden the IBW of the antenna, the conventional Γ-shaped feed is changed into a branch structure. The IBW of the finally designed antenna reaches 56.8% (2.91-5.22 GHz). In the whole operational bandwidth, the radiation pattern in E-plane realizes the half power beam width (HPBW) of more than 110°, and the H-plane radiation pattern realizes the HPBW of more than 160°. The maximum width of E-plane HPBW is 175°, and the maximum width of H-plane HPBW is 229°.
