Abstract
A strip line-type high-frequency element constituted by a laminate including a first ground conductor electrode substrate 2; a substrate 3 having a first strip line electrode 3a of less than one turn having a through-hole round electrode 3e; a substrate 4 having a second strip line electrode 4a of one or more turns having a through-hole electrode 4f; a substrate 5 having a third strip line electrode 5a of one or more turns having a through-hole round electrode 5e; a substrate 6 having a fourth strip line electrode 6a of less than one turn having a through-hole electrode 6f; a second ground conductor electrode substrate 7; and a protective substrate 8, wherein the through-hole round electrode 3e of the first strip line electrode 3a is connected to the through-hole electrode 4f of the second strip line 4a to form a first line, and the through-hole round electrode 5e of the third strip line electrode 5a is connected to the through-hole electrode 6f of the fourth strip line 6a to form a second line, one of the first and second lines being a main line while the other being a sub-line, whereby the strip line-type high-frequency element functions as a directional coupler.
