Thirdly, a CPW-CPW transition is presented, which changes the size of CPW while keeping the characteristics impedance of CPW unchanged and can be used to connect the printed antenna above or other CPW feed line to a given size coax.

• 第三，提出了一种共面波导间的过渡连接(CPW-CPW变换)，这种变换在保持共面波导特性阻抗不变的前提下改变其具体尺寸，可用来将上述印刷缝隙天线或其它特定的共面波导馈线与给定尺寸的同轴接头相连接。
