Antenna unit () comprising a flexible or bendable printed circuit board, PCB, (), being divided into a number of sections (), each section () being delimitated from another section () by a straight folding line (). At least one section () accommodates an antenna element (), and at least another adjacent section () is either accommodating an antenna element () having a terminal area () or is a terminal area (). The antenna element is coupling to the terminal area () for feeding the antenna element (), the adjacent sections () of the PCB being folded along the corresponding delimitating folding line () and being kept in or keeping a fixed position, such that the adjacent sections () are arranged at respective angles while each section () is maintaining a substantially plane configuration.

The present invention relates to a microwave signal transition component () having a first signal conductor side () and a second signal conductor side (). The signal transition component () is arranged for transfer of microwave signals from the first signal conductor side () to the second signal conductor side (). The transfer component () comprises at least one, at least partly circumferentially running, electrically conducting frame (), a dielectric filling () positioned at least partly within said conducting frame (), at least one filling aperture () miming through the dielectric filling, and, for each filling aperture (), an electrically conducting connection () that at least partly is positioned within said filling aperture (). The present invention also relates to a method for manufacturing a microwave signal transition component according to the above.
