Patent number: 9912078Abstract: The invention provides an antenna arrangement having an operating frequency band with a mean wavelength ? and comprising at least two columns of antenna elements with at least two antenna elements in each column. Each column of antenna elements extends above a separate elongated column ground plane with a column separation defined as a distance between mid-points of neighbouring column ground planes. The antenna elements in each column are located along a column axis pointing in a longitudinal direction of the column ground plane wherein all column separations are below 0.9? and wherein a parasitic element extends above at least one antenna element in each column. Parameters of the parasitic element are adapted for proper excitation thus achieving a reduced beamwidth for each of said columns of antennas. The invention also provides a method to manufacture the antenna arrangement.Type: GrantFiled: November 1, 2010Date of Patent: March 6, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Henrik Jidhage, Anders Ek

Patent number: 9692142Abstract: 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*?0, where ?0 is the wavelength for the center frequency of the frequency band for which the inverted F antennas are intended.Type: GrantFiled: January 29, 2016Date of Patent: June 27, 2017Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Anders Ek, Ola Kaspersson, Håkan Karlsson
