技術摘要 / Abstract
A vertical-transition structure comprises a microstrip line and a combination of a coaxial connector and a metallic ring underneath the microstrip line. A first through hole is created next to the microstrip line and near one end of its signal line. The metallic ring has a second through hole. The coaxial connector has a center conductor including an extended portion to be inserted into the second through hole via its center, and subsequently through the first through hole to connect to the signal line vertically. Specially, the extended portion is not inserted through the center of the first through hole. The present structure can improve the high-frequency insertion loss of the vertical transition caused by the sudden change of electromagnetic field distributions from a coaxial line to a microstrip line and the resonant response of the coaxial connector, and therefore, increase the 1-dB transmission passband of the vertical transition substantially.
