发明名称 PHASE SHIFTER
摘要 A phase shifter includes a metal plate, a support portion, a slot, a coupling portion, and a ground portion. The phase shifter effectively improves signal coupling efficiency, and inhibits noise generated with the change of phase shift due to signal transmission. The phase shifter is advantageous in smaller volume, easy to assemble, and low cost.
