Abstract
A transmission arrangement for a radio station of an access system may include a printed circuit board with an upper main surface and a first metallization plane in which conducting paths are formed. A drive circuit for supplying a frequency signal and an antenna structure are also provided. The antenna structure includes a coupling device, a conductor structure and a continuous, electrically conductive path having first and second ends opposite each other. The coupling device is configured to couple a frequency signal supplied by the drive circuit into the conductor structure. The first and/or second ends form end(s) of the conductor structure. The printed circuit board is retained at a distance from the first and/or second end by a gas or an electrically non-conductive material.
