Patent number: 9306266Abstract: A multi-band antenna includes a ground plane, a single antenna element, a frequency multiplexing circuit and at least two feeding strips coupled between the frequency multiplexing circuit and the single antenna element. Furthermore, the feeding of the antenna is arranged by one or more feeding points arranged between the ground plane and the frequency multiplexing circuit. According to first implementation one feeding point is arranged for at least two antenna branches. The signal fed into the feeding point is multiplexed by the multiplexing circuit to the antenna branches. According to at least one other implementation a dedicated feeding point is arranged for each of the antenna branches. At the same time the isolation of the frequencies between the different branches is arranged. This can be achieved e.g. by a multiplexing circuit. Moreover, impedance of the antenna branches can be matched with matching circuitry.Type: GrantFiled: September 21, 2012Date of Patent: April 5, 2016Assignee: AALTO UNIVERSITY FOUNDATIONInventors: Risto Valkonen, Janne Ilvonen
