Inverted F-antennas at a wireless communication node
First Claim
1. A node in a wireless communication arrangement, the node comprising:
- an antenna arrangement comprising;
a base having a top side lying in a first plane and an opposite bottom side lying in a second plane parallel with the first plane;
a first inverted F antenna; and
second inverted F antenna,the first inverted F antenna comprising a first feed connection, a first ground connection and a first radiating element mainly extending from the first ground connection along a first longitudinal extension and being positioned above the top side of the base and lying in a third plane that is parallel with and spaced apart from the top side of the base, the first feed connection connected to the first radiating element and extending along a line that is perpendicular with the top side of the base,the second inverted F antenna comprising a second feed connection, a second ground connection and a second radiating element mainly extending from the second ground connection along a second longitudinal extension and being positioned above the top side of the base and lying in said third plane, the second feed connection connected to the second radiating element and extending along a line that is perpendicular with the top side of the base,the first radiating element and the second radiating element extending in opposite directions along their respective longitudinal extensions from the respective ground connections, andthe first longitudinal extension and the second longitudinal extension being mutually parallel, where the closest distance between the first radiating element and the second radiating element exceeds 0.4*λ
0, where λ
0 is the wavelength for the centre frequency (f0) of a frequency band (fB) for which the first and second inverted F antennas are intended.

Abstract
The disclosure relates to a node in a wireless communication arrangement, the node comprising an antenna arrangement that comprises a first and second inverted F antenna. The inverted F antennas comprise a corresponding first and second feed connection, first and second ground connection and a corresponding first and second radiating element mainly extending from the respective ground connection along a corresponding first and second longitudinal extension. The inverted F antennas are arranged on, or in, a plane. Furthermore, the first and second radiating elements are extending in opposite directions along their respective longitudinal extensions from the respective ground connections, the first longitudinal extension and the second longitudinal extension being mutually parallel. The closest distance between the first radiating element and the second radiating element exceeds 0,4*λ0, where λ0 is the wavelength for the centre frequency of the frequency band for which the inverted F antennas are intended.
