In order to achieve beam switching, and under the premise of reducing the cost of using the combination of switching and transmission-line phase-shift unit.
为了实现波束的切换，并且在降低成本的前提下使用了开关与传输线组合的移相单元。
The results show that the figure of merit and the differential phase shift of the phase shifter are larger than these of rectangular waveguide phase shifter under the same condition.
结果表明，该移相器的优值和差相移比同一条件下的矩形波导的同类移相器的大。
