Abstract
Antenna element (1) for a multi-radiator antenna arrangement, the antenna element comprising a conductive antenna element (2) body having radiating portions (3a-d), the antenna element further comprising a feeding network electrically connected to the radiating portions, the feeding network comprising transmission lines, each having a central conductor (4a-d) and a ground conductor (5a-d), wherein the ground conductor partially surrounds the central conductor and is formed integrally with the antenna element body.
Claims25
An antenna element (1) for a multi-radiator antenna arrangement, the antenna element comprising a conductive antenna element (2) body having radiating portions (3a-d), the antenna element further comprising a feeding network electrically connected to the radiating portions, the feeding network comprising transmission lines, each having a central conductor (4a-d) and a ground conductor (5a-d), wherein the ground conductor partially surrounds the central conductor and is formed integrally with the antenna element body..
Antenna element according to any of the preceding claims, wherein the antenna element body (2) is integrally formed.
Antenna element according to any of the preceding claims, wherein said antenna element body (2) comprises said radiating portions (3a-d) in the form of radiating portions formed spaced apart from each other at a periphery of the antenna element.
Antenna element according to any of the preceding claims, further comprising at least one non-conductive holding element (8a, 8b, 9) arranged to hold the central conductors in position in relation to the ground conductors and the antenna element body.
Antenna element according to any of the preceding claims, wherein the antenna element body (2) is substantially bowl-shaped.
Antenna element according to any of the preceding claims, wherein adjacent radiating portions (3a-d) are formed substantially perpendicularly relative each other.
A dual-band antenna element arrangement comprising an antenna element (1) according to any of the preceding claims being configured to transmit and receive signals within one or more first frequency bands, and a high-band antenna element (10) configured to transmit and receive signals within one or more second frequency bands being higher than said one or more first frequency bands, wherein the high-band antenna element comprises radiating portions (10a-d) and is arranged substantially at a center of the antenna element (1) at least partly within a space defined by the antenna element body (2) of the antenna element.
