Inverted F-Antennas at a Wireless Communication Node
First Claim
1. A node (1) in a wireless communication arrangement (W), the node (1) comprising:
- an antenna arrangement (2) comprising;
a first inverted F antenna (3) and a second inverted F antenna (4),the first inverted F antenna (3) comprising a first feed connection (5), a first ground connection (6) and a first radiating element (7) mainly extending from the first ground connection (6) along a first longitudinal extension (8),the second inverted F antenna (4) comprising a second feed connection (9), a second ground connection (10) and a second radiating element (11) mainly extending from the second ground connection (10) along a second longitudinal extension (12),the first inverted F antenna and the second first inverted F antenna being arranged on, or in, a plane (13),the first radiating element (7) and the second radiating element (11) extending in opposite directions along their respective longitudinal extensions (8, 12) from the respective ground connections (6, 10), andthe first longitudinal extension (8) and the second longitudinal extension (12) being mutually parallel, where the closest distance (14) between the first radiating element (7) and the second radiating element (11) 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.
