COUPLING DEVICE FOR COUPLING THE INTERIOR GPS ANTENNA SIGNAL AND THE EXTERIOR GPS ANTENNA SIGNAL

摘要

The present invention relates to an internal and an external GPS antenna signal router (300), GPS signal reception sensitivity and as the durability is excellent, and in a low cost implementation, it relates to an external GPS antenna signal router 300. The present invention is a built-in antenna signal input terminal; A first capacitor one end connected to the built-in antenna and the signal input terminal (304a); External antenna signal input terminal; Once the second capacitor is connected to the external antenna and the signal input (304b); And the other terminal receiving the phase shift signal is transmitted from the other terminal connected to the first capacitor of the second capacitor (304b) and the second signal is sent from a capacitor (304a) (304b) of said first capacitor (304a) a signal combiner for combining a 0 (303); And the first capacitor (304a) and the second capacitor and the signal transmission line to connect the coupler (303) (304b) and an impedance matching resistor to match the impedance of the transmission line connecting the signal combiner 303 (305 ), characterized in that provided for the internal and external GPS antenna provides a signal router (300).
