Abstract

PURPOSE:To give the reverse turning to the circular polarized electric wave as well as to give a fixed phase change with the mechanical turn only by securing a relative turning between the right-turning circular polarized wave antenna and the left- turning circular polarized wave antenna. CONSTITUTION:The right-turning circular polarized electric wave received through receiving crossed dipole antenna 1 passes through feeder 3 with twisted transmission lines 3a and 3b and is then radiated through transmitting crossed dipole antenna 2 and in the form of the left-turning circular polarized electric wave. In this case, antenna 2 is turned by angle theta against antenna 1. Thus, the radiated left-turning circular polarized wave receives a phase change to the received right-turning circular polarized wave and in accordance with the length of feeder 3 and turning angle theta of antenna 2. And in case angle theta is changed with the fixed length of feeder 3, the changing phase amount can be changed in a comparatively easy way. The same function is also available when antenna 1 receives the left-turning circular polarized electric wave.
