Phase Shifter And Antenna Including Phase Shifter |
摘要 |
A phase shifter includes two or more conductive strips, an input line and a wiper coupled to both the input line and the conductive strips. Rotation of the wiper about a pivot point alters the path lengths between the input line and output ports or antenna elements connected to the conductive strips. The wiper is a multi-bladed wiper. Phase errors in multi-bladed wiper-type phase shifters are reduced. Arrangements for reduction of phase shifter size or increase in phase shift range are described.
