摘要： A directional coupler includes a first to a fourth port, a main line connecting the first port and the second port, a first and a second subline section configured to be electromagnetically coupled to the main line, and a phase shifter. The first subline section, the phase shifter, and the second subline section are arranged in this order in series between the third port and the fourth port. The phase shifter outputs a signal that is phase-delayed relative to an input signal. The phase delay amount of the output signal of the phase shifter relative to the input signal increases with increasing frequency of the input signal. A frequency twice as high as the frequency of the input signal at which the phase delay amount is 90 degrees is lower than the frequency of the input signal at which the phase delay amount is 180 degrees.

摘要： The auxiliary ground layer is a part in which the main line and the sub line do not overlap in the lamination direction and is disposed to face a part in which a distance from the first ground layer and a distance from the second ground layer are different in the lamination direction. When a longer distance is set as a first distance a and a shorter distance is set as a second distance b between a distance between the non-overlapping part and the first ground layer and a distance between the non-overlapping part and the second ground layer, and a third distance between the non-overlapping part and the auxiliary ground layer is set as c, the relationship of a>c≥b is satisfied.

摘要： An antenna device 1 has a capacitive coupling element 10 mounted on a printed circuit board 20. Strip patterns 21 to 23 are provided in a grand clearance region 20A defined on one principal surface of the printed circuit board 20. The strip pattern 21 is connected to a feeding line 29 after extending in a first direction from the connecting point with the capacitive coupling element 10. The strip pattern 22 is connected to a feeding line 30 after extending in a second direction, that is an opposite to the first direction, from the connecting point. The strip pattern 23 is connected to a ground pattern 24 after extending in a third direction from the connecting point. The capacitive coupling element 10 is disposed with an offset toward the first direction. The strip pattern 21 is shorter in length than the strip pattern 22.

摘要： A filter circuit includes two ports, a first resonant circuit, and a second resonant circuit. The first resonant circuit is provided between the two ports in a circuit configuration and coupled with both of the two ports. The second resonant circuit is provided between the two ports in the circuit configuration and coupled with at least one of the two ports. Coupling of the second resonant circuit and the two ports is weaker than coupling of the first resonant circuit and the two ports.

摘要： A directional coupler includes: a first to a fourth port; a main line connecting the first and second ports; a first to a fourth subline section electromagnetically coupled to the main line; a first to a third matching section; and a stack. The first subline, first matching, third subline, third matching, fourth subline, second matching, and second subline sections are arranged in this order between the third and fourth port. The first and second matching sections include an inductor connecting two subline sections located on opposite sides of the matching section. Each of one or more conductor layers used to form the inductor includes two connection portions for electrical connection to respective other elements, and a line portion connecting the two connection portions. The inductor excluding the connection portions does not include potions that overlap each other when viewed in the stacking direction of the stack.
