摘要:
In order to transmit a signal received in a GPS antenna (20) to a GPS receiver body (30) through a glass plate (40), a signal transmission circuit (10) is divided into first and second signal transmission parts (11, 12). The first signal transmission part (11) is for transmitting a high frequency signal from an output terminal (20out) of the GPS antenna (20) to a first surface (41) of the glass plate (40). The second signal transmission part (12) is for transmitting the high frequency signal from a second surface (42) of the glass plate (40) to an input terminal (30in) of the GPS receiver body (30). The first signal transmission part (11) includes a first coaxial cable (111), a first electrode pair (112), a first balanced line (113), and a first balun (114). The second signal transmission part (12) includes a second coaxial cable (121), a second electrode pair (122), a second balanced line (123), and a second balun (124).
