Patent number: 11879922Abstract: The present invention discloses an antenna arrangement for 4.5G or 5G base station testing purposes. The antenna elements are placed in concentric rings and in a star-shaped arrangement around a center spot. All antenna elements within the same ring are controlled by the same amplitude and phase control signal. The test system processor also selects dedicated rings into use and switches the rest of the rings off. The ring spacing, i.e. the mutual antenna element distance along the same radial line will be determined based on highest frequency within the desired wide frequency band. A bowtie dipole type of antenna can be used. The antenna elements can be fixed on a printed circuit board, and thus, they remain mechanically stationary.Type: GrantFiled: October 3, 2019Date of Patent: January 23, 2024Assignee: Orbis Systems OyInventors: Mika Kiiskilä, Tuomo Tolonen, Matti Tervo
