Abstract
Antenna arrangement comprising an antenna feeding network comprising first set(s) of transmission lines and second set(s) of transmission lines and set(s) of high-band radiating elements, set(s) of low-band radiating elements. The radiating elements are arranged at a front side of a backplane. Set(s) of high-band radiating element(s) is/are connected to the first set(s) of transmission lines. Set(s) of low-band radiating elements is/are connected to the second set(s) of transmission lines. The first set(s) of transmission lines is/are located at a rear side of the backplane between the backplane and a first plane parallel to the backplane. The second set(s) of transmission lines is/are located between the first plane and a second plane being parallel to the first plane.
Claims26
An antenna arrangement, the antenna arrangement comprising:
- an antenna feeding network comprising at least one first set of transmission lines and at least one second set of transmission lines, wherein the transmission lines of the at least one first and second sets of transmission lines comprise inner and outer conductors, and
- at least one set of high-band radiating elements, and at least one set of low-band radiating elements, the radiating elements being arranged at a front side of a backplane (4a;
- 104) of the antenna arrangement,
- wherein one or more of the at least one set of high-band radiating elements is each connected to one or more of the at least one first set of transmission lines, and wherein one or more of the at least one set of low-band radiating elements is each connected to one or more of the at least one second set of transmission lines,
- wherein the at least one first set of transmission lines is located at a rear side of the backplane between the backplane and a first plane parallel to the backplane, and
- wherein the at least one second set of transmission lines is located between the first plane and a second plane being parallel to the first plane.
