This paper presents the phase control of circularly pblarized wave from a slot with a parasitic dipole. The authors adopted these elements and proposed a single-layer linear-to-circular polarization converter consisting of a dipole array to be mounted on an existing narrow-wal slotted waveguide array as in Fig.1. The coupling between one slot and one parasitic dipole is discussed. By using the simple approximation for the induced currents on the dipole, we express the amplitude and the phase of circular polarization in analytical forms. This expression clearly explains all the behavior of circular polarization. An important result amongst all is that the phase of circular polarization is determined only by the dipole angle and is independent of that of the slot. These relations are also confirmed by experiments using a waveguide slot with a parasitic dipold above it.
