摘要： The present invention relates to a wideband I-shaped monopole dipole including a first dipole unit, a second dipole unit, a feed device, a parallel-wire and two double-leads disposed between two cantilevers of the first dipole unit and the second dipole unit. The parallel-wire connects the first dipole unit with the second dipole unit in a parallel connection. The feed device includes a feed pad and a coaxial cable. The double-leads between the cantilevers of the first and second dipole units extend to form two parallel plates acting as a first balancer and a second balancer to balance impedance components ofthe first and second dipole units. Afeedpoint of the feed device is disposed on a center portion of the parallel-wire. The feed pad is provided on one line of the parallel-wire. Outer and inner conductors of the coaxial cable are respectively coupled to the feed pad and the other line of the parallel-wire. According to the present invention, a wide band capability and a radiation characteristic with a high front-back ratio can be obtained without changing the size of a metallic-based reflective plate. Additionally, simplified configuration of the wideband I-shaped monopole dipole can also facilitate assembling and maintaining as well as reduce the manufacturing cost.
摘要翻译： 本发明涉及一种宽带I型单极偶极子，包括第一偶极子单元，第二偶极子单元，馈电装置，平行线和设置在第一偶极子单元和第二偶极子单元的两个悬臂之间的两个双引线 。 并联线将第一偶极子单元与第二偶极子单元并联连接。 进料装置包括进料垫和同轴电缆。 第一和第二偶极子单元的悬臂之间的双引线延伸以形成用作第一平衡器的两个平行板和用于平衡第一和第二偶极子单元的阻抗分量的第二平衡器。 进给装置的供给点位于平行线的中心部分。 馈电垫设置在平行线的一条线上。 同轴电缆的外部和内部导体分别耦合到馈电垫和平行线的另一条线。 根据本发明，可以在不改变金属基反射板的尺寸的情况下获得具有高前后比的宽带能力和辐射特性。 此外，宽带I型单极偶极子的简化配置也可以方便组装和维护以及降低制造成本。
