ULTRA-HIGH FREQUENCY TRANSITION APPARATUS FOR IMPROVING TRANSMISSION CHARACTERISTICS AT MILLIMETER WAVE BAND

摘要

An ultra-high frequency transmitting device is provided to relieve discontinuity of electric field in a junction region between a strip transmission line and a micro strip transmission line by using a signal matching ground. An ultra-high frequency transmitting device includes a strip transmission line(strip), a micro strip transmission line(Mstrip), and a signal matching ground(Stuning). The strip transmission line is arranged inside a multilayer substrate. The micro strip transmission line is arranged outside the multilayer substrate. The micro strip transmission line is connected to the strip transmission line. The signal matching ground is positioned in a bottom surface of the micro strip transmission line. The signal matching ground is extended from the micro strip transmission line to the strip transmission line. The signal matching ground is connected to a ground(GND2) positioned in a bottom layer of the multilayer substrate.
