A composite electronic component includes a multilayer stack, a filter, and an antenna. The filter is located within the multilayer stack and interposed between a first ground conductor layer and a second ground conductor layer. The antenna includes a radiation element. The radiation element is located on a side of the second ground conductor layer opposite from the first ground conductor layer. When viewed in a direction parallel to the stacking direction of the multilayer stack, the radiation element entirely lies inside the perimeter of the second ground conductor layer. The multilayer stack includes a plurality of connection conductor sections arranged around the filter and connecting the first ground conductor layer and the second ground conductor layer.

A circuit board is provided. The circuit board includes a substrate, a waveguide line and a laminated waveguide. The waveguide line is at least partially positioned on a first surface of the substrate. The waveguide line transmits a high frequency signal. The laminated waveguide is formed inside the substrate. The laminated waveguide is electromagnetically coupled to the waveguide line, and has a lead-out portion led out from inside the substrate to a surface other than the first surface. The laminated waveguide includes a dielectric layer, a pair of main conductive layers and a through conductor group. The pair of main conductive layers sandwiches the dielectric layer in a thickness direction thereof. In the through conductor group, a plurality of through conductors are arranged along a high frequency signal transmitting direction. The plurality of through conductors electrically connect the pair of main conductive layers.

A microwave transmission line includes a substrate of high-resistivity silicon, a first dielectric film and a second dielectric film successively formed on the principal surface of the substrate and having different compositions, and a conductor film formed with at least the first dielectric film interposed between the conductor film and the substrate.

The invention relates to a waveguide manufacturing and a waveguide manufactured with the method, which can be integrated into a circuit structure manufactured with the multilayer ceramic technique. The core part (23, 33, 43, 53a, 53b, 53c) of the waveguide is formed by a unit assembled of ceramic layers, which is limited in the yz plane by two impedance discontinuities and in the xz plane by two planar surfaces (24, 25, 34, 35, 54a, 54c, 55a, 55b, 55c) made of conductive material. The conductive surfaces can be connected to each other by vias made of conductive material (38, 39, 48, 49). The waveguide manufactured with the method according to the invention is a fixed part of the circuit structure as a whole.

A semiconductor integrated circuit structure including a semiconductor substrate having a large area adapted for a large scale integration, a circuit formed in the substrate for generating a pair of complementary signals, a pair of common potential level layers with an electrically insulating layer interposed therebetween, the common potential level layers being formed above and being electrically insulated from the substrate, and a pair of electric conductor pattern layers formed in the insulating layer for conducting the pair of complementary signals. The electric conductor pattern layers are arranged so as to be overlapped with each other in a direction substantially perpendicular to the large area substrate and so as to be substantially parallel with the large area substrate. The overall length of the electric conductor pattern layers is such that when an electric signal is conducted through an electric conductor in an IC having a length equal to the above-mentioned overall length, attenuation of the signal thereby is not negligible.

A transmission path for a pulse-type communication system comprises two flat outer conductors and one flat inner conductor separated from one another by layers of dielectric material such as Teflon. The maximum effective thickness of the conductors is on the order of magnitude of the penetration depth of the current. The stack of conductive and nonconductive layers is flanked by two ferrite strips of the same height as the stack and in contact therewith, these strips serving to gather the laterally emanating lines of force into closed loops alongside the stack. At least one of the strips may be subdivided into sections separated by gaps through which branch leads can extend into contact with the flat conductors.
