Abstract

PURPOSE: To make assembly easy by constituting a 3dB directional coupler and/or balloon as microstrip lines formed on a printed circuit board corresponding to the fitting board of a helical element.
CONSTITUTION: On a printed circuit board 10 composed of upper and lower printed circuit boards 30 and 20, a cylindrical helical element 70 is installed and on the outer peripheral surface of this helical element 70, a helical line 71 is formed. On the upper and lower surfaces of the lower printed circuit board 20, solid ground patterns are respectively formed and on the other hand, a 3dB directional coupler 40 is formed as the microstrip line on the inner layer. On the lower printed circuit board 20, a terminal insert port 23a and through holes 23b-23d are respectively formed and connected to a land formed as one part of the microstrip line of the 3dB directional coupler 40. After installing the helical element 70 on this printed circuit board, a connecting member is fitted between the helical line on the helical element side and the terminal of the microstrip line on the printed circuit board side. Thus, the helical antenna can easily be assembled with simple structure.
