Embodiment Construction

[0031] exist figure 1 , shows a front view of a dual orthogonally polarized array antenna comprising nine dual polarized antenna elements 2, 3, 4, 5, 6, 7, 8 arranged in column 11 , 9, 10. Each antenna element 2, 3, 4, 5, 6, 7, 8, 9, 10 is arranged to radiate electromagnetic energy having a first vertical polarization and a second horizontal polarization. The column 11 extends along the longitudinal extension of the array antenna 1 , and the array antenna 1 has a first end 12 and a second end 13 . Each antenna element 2, 3, 4, 5, 6, 7, 8, 9, 10 is shown in the form of two crossed orthogonal slots, where each vertically oriented slot 14h, 15h, 16h, 17h, 18h, 19h, 20h, 21h, 22h (oriented along the longitudinal extension of the array antenna 1) are related to horizontal polarization, each horizontally oriented slot 14v, 15v, 16v, 17v, 18v, 19v, 20v, 21v, 22v (ie oriented vertically with respect to the longitudinal extension of the array antenna 1 ) is related to the vertical p...

Abstract

The present invention relates to a dual polarized array antenna (1, 31) comprising at least two dual polarized antenna elements (2, 3, 4, 5, 6, 7, 8, 9; 32, 33, 34, 35, 36, 37, 39, 40) being arranged for radiating electromagnetic 5 energy having a first polarization, constituting a first antenna radiation pattern, via a connection to a first antenna port (28), and electromagnetic energy having a second polarization, constituting a second antenna radiation pattern, via a connection to a second antenna port (29), the second polarization being orthogonal to the first polarization, the first antenna radiation pattern and second antenna radiation pattern each having a main beam and a number of side-lobes with nulls. The array antenna (1, 31) comprises at least one further dual polarized antenna element (10, 38) arranged for radiating electromagnetic energy having two mutually orthogonal polarizations, constituting further antenna radiation patterns, via respective connections to the first antenna port (28) and the second antenna port (29), where the polarization of said at least one further dual polarized antenna element (10, 38) that is associated with the first antenna port (28) deviates from the first polarization such that said at least one null of the first antenna pattern is at least partly filled.

Description

technical field [0001] The invention relates to a dual polarized array antenna comprising an arrangement for radiating electromagnetic energy having a first polarization, constituting a first antenna radiation pattern, via a connection to a first antenna port and radiating via a connection to a second antenna port having a Second polarization, at least two dual-polarized antenna elements of electromagnetic energy constituting a second antenna radiation pattern, the second polarization being orthogonal to the first polarization, the first antenna radiation pattern and the second antenna radiation pattern Each has a main beam and a plurality of side lobes, where a null is located at an angular position between a side lobe and an adjacent side lobe or adjacent main beam. Background technique [0002] For today's mobile communication transmissions, such as MIMO, it is often desirable to use dual polarized antennas. Typically, a dual polarized antenna comprises a first number of...
