    Abstract: A multiband radiating array according to the present invention includes a vertical column of lower band dipole elements and a vertical column of higher band dipole elements. The lower band dipole elements operate at a lower operational frequency band, and the lower band dipole elements have dipole arms that combine to be about one half of a wavelength of the lower operational frequency band midpoint frequency. The higher band dipole elements operate at a higher frequency band, and the higher band dipole elements have dipole arms that combine to be about three quarters of a wavelength of the higher operational frequency band midpoint frequency. The higher band radiating elements are supported above a reflector by higher band feed boards. A combination of the higher band feed boards and higher band dipole arms do not resonate in the lower operational frequency band.

    Abstract translation: 根据本发明的多频带辐射阵列包括一个下层偶极子元件的垂直列和一个较高频带偶极子元件的垂直列。 低频带偶极子元件在较低的工作频带下工作，低频带偶极子元件具有组合为较低工作频带中点频率的波长的约一半的偶极臂。 较高频带偶极子元件在较高频带上工作，较高频带的偶极子元件具有组合为较高工作频带中点频率波长的约四分之三的偶极臂。 较高频带辐射元件通过较高频带馈电板支撑在反射器上方。 较高频带馈电板和较高频带偶极臂的组合在较低工作频带中不会谐振。

    Abstract: A base station antenna, comprising a first reflector structure having first and second generally opposed sides; a first array of radiating elements that are mounted to extend outwardly from the first side of the first reflector structure and a second array of radiating elements that are mounted to extend outwardly from the second side of the first reflector structure; a second reflector structure having third and fourth generally opposed sides; and a third array of radiating elements that are mounted to extend outwardly from the third side of the second reflector structure and a fourth array of radiating elements that are mounted to extend outwardly from the fourth side of the second reflector structure, wherein the first side is a first distance from the second side and the third side is a second distance from the fourth side, and wherein the second distance is different from the first distance.

    Abstract: Providing a multiband antenna, comprising a column of lower band dipole elements that operate in a lower operational frequency band and a column of higher band dipole elements that operate in a higher operational frequency band, each higher band dipole element includes a higher band feed board and a dipole having a first dipole arm and a second dipole arm, it is an objective to reduce distortion in the radiation pattern of the lower operational frequency band. This is solved by, for each higher band dipole element, the length of the combination of the higher band feed board and the first dipole arm exceeds one quarter of a wavelength of the lower operational frequency band and tunes a common mode resonance to be out of the lower operational frequency band.
