Abstract

An antenna comprises a coil element comprising a core element and coil wound around the core element, the core element arranged along a longitudinal direction and having a first front surface and a second front surface. A first metallic plate element and a second metallic plate element are provided. The first metallic plate element is arranged on a first side of the core element and extends with its first end in the longitudinal direction beyond the first front surface of the core element and its second end in the longitudinal direction adjacent the core element. The second metallic plate element is arranged on a second side of the core element opposite said second side and extends with its first end in the longitudinal direction beyond the second front surface of the core element and its second end in the longitudinal direction adjacent the core element.
