PURPOSE: A high directional coupler for mobile communication is provided to reduce the effects of a parasitic capacitance generated between a first and a second signal line, thereby improving the directionality of the coupler. CONSTITUTION: A high directional coupler for mobile communication includes a housing (10), a substrate (30), and a pair of ground pins (11). The housing provides a housing space. The substrate has a first and a second signal line. The first and the second signal line are placed in the housing space. The first and the second signal line couple input signals, and output the coupled signals. The ground pins are respectively placed at both ends of a portion in which the first and the second signal line are mutually adjacent. |
