    Abstract: An electronic component which is employed in the frequency range in the microwave band or above is mounted on a circuit board. The circuit board comprises two linear transmission line members, a ground electrode, and an electric insulating substrate provided with the transmission line members and the ground electrode on its major surface. The electronic component comprises external electrodes which are formed on its side surfaces. Holding patches which are formed on the lower surface of the electronic component are bonded to the ground electrode by solder members, thereby fixing the electronic component to the circuit board. At this time, small clearances are defined between the electronic component and the circuit board through the solder members, whereby the external electrodes are electromagnetically coupled with the transmission line members and the ground electrode through the clearances respectively. Thus, it is possible to obtain a mounting structure for an electronic component, which can suppress development of unnecessary inductance components.

    Abstract: A printed circuit board includes a first electrically conductive reference plane configured to distribute a first reference voltage applied thereto across a surface area of the first reference plane, and a second electrically conductive reference plane extending parallel to the first reference plane, and configured to distribute a second reference voltage applied thereto across a surface area of the second reference plane. A first layer is provided, which extends between the first reference plane and the second reference plane, and includes one or more first signal lines extending adjacent the first reference plane. The first layer is divided into: (i) a first region in which the one or more first signal lines are disposed, (ii) a second region containing an additional plane that is configured to receive a third voltage and has smaller surface area relative to the surface areas of the first and second reference planes, and (iii) a third region containing a dielectric layer. A second layer is provided, which extends between the first reference plane and the second reference plane, and includes one or more second signal lines extending adjacent the second reference plane. The second signal lines have linewidths that vary as a function of whether they are vertically aligned with the first region, the second region, or the third region.
