Abstract

A transmission line structure suited as a transmission path for antenna feed in base stations. The circuit board technique is applied to the manufacture of a transmission line structure (400) for implementing an air-insulation between the centre and ground conductor of the transmission line. The circuit board is a multi- layer board, and a microstrip (440) functions as the line centre conductor. Material has been removed from adjacent layers (432, 433) at the centre conductor and its sides, and a cavity thus formed functions as an air-insulation between the centre conductor (440) and ground conductor (410) of the transmission line. The ground conductor is a part of the metal body of the device containing the transmission line. The structure can comprise several transmission lines, each of which has a cavity of its own in the same multi-layer board. The structure can also be two- sided so that there are similar cavities and a ground conductor on each side of the layer, which comprises the centre conductor(s). The losses of a transmission line are relatively low, and its production costs also are relatively low. Other functional parts, such as directional coupler and power divider, can be integrated to the structure without adding the stage number of the manufacture.
