Abstract

PURPOSE:To ensure an optional variation for the phase of a high frequency signal, by forming plural strip lines having the same impedance as that of a feeder on a substrate and selectively connecting in switch these strip lines to the feeder. CONSTITUTION:Strip lines 85-95 having different lengths and the same impedance as that of a feeder that transmits the high frequency signal are formed on a printed distributing panel 70. These strip lines are selectively connected in switch to the feeder by means of a rotary switch to vary the length of the strip line, i.e. the impedance. Thus the phase of the high frequency signal is varied. In addition, a strip line 96 having nearly the same length as an ineffective line length is formed on the same plane of the panel 70 and inserted to the line having no variable length. Thus an equal length is always secured for the ineffective line regardless of the length of an external line which is going to and coming back from both lines.
