Abstract
The present invention relates to a surface mounted coil (200) for wireless communication. The coil (200) comprises a wire (202) wounded about a core (204) thereby establishing a plurality of windings and having its ends terminated on mounting sections (208) at each end of the core (204). The coil (200) further comprises a shielding layer (212, 300) wound about a central part of the core (204) thereby covering said windings. The shielding layer (212, 300) comprises a shielding pattern and a contact section (214) for connecting to a ground level and to the shielding pattern.
