摘　　要：A Ka-band wideband microstrip-to-microstrip(MS-to-MS)vialess vertical transition on slotline multimode resonator(MMR)is presented.The proposed transition mainly consists of a slotline MMR on the common ground plane,and two microstrip(MS)lines facing each other at the top and third layers in the four-layered liquid crystal polymer(LCP)substrate.In order to improve the bandwidth of the proposed transition,a U-shaped branch is added to the top-and third-layer MS lines,separately.The slotline MMR can be properly excited by setting the position of the U-shaped branch line.As such,a three-pole wideband vertical transition is obtained,which shows a good transmission performance over a wide frequency range of 29.27-39.95 GHz.The three-pole wideband vertical transition based on multilayer LCP substrate is designed,fabricated,and measured.Test results indicate that a wide frequency range of 26.8436.26 GHz can be obtained with return loss better than-10dB and insertion loss less than-3dB.
