    摘要: A slot antenna comprising a dielectric substrate, a high-frequency signal transmission line formed on one surface of said dielectric substrate and having an open end, and a ground layer formed on the other surface of said dielectric substrate, said ground layer having a slot at a position opposed to the open end of said transmission line, wherein a dielectric plate for impedance matching is laminated on the surface of said ground layer on the side where said slot is formed so as to cover said slot. The slot antenna not only features a high antenna efficiency but also can be easily and cheaply produced by a layer-laminating method which is a generally employed technology for producing multi-layer wiring substrates. Besides, the slot antenna has a very simple structure which is small in size and is light in weight, and can be very well adapted to the systems that require these characteristics.

    摘要: A high-frequency semiconductor device contains a semiconductor element in a cavity formed by a dielectric board and a cap. A first high-frequency transmission line connected to the semiconductor element is formed on the surface of said dielectric board in said cavity and a second high-frequency transmission line is formed on the bottom surface of said dielectric board, so that said first high-frequency transmission line and said second high-frequency transmission line are electromagnetically coupled together. In this semiconductor devise in which the first transmission line and the second transmission line are electromagnetically coupled together, the transmission lines need not be passed over the side wall of the cap, and neigther reflection loss or radiation loss takes place on the side wall. Besides, transmission loss of high-frequency signals is caused by neigther through-holes or via-holes, and is effectively suppressed.

    摘要: In the production of a 124-type or 123-type superconductor by a sol-gel method using alkoxides of respective metals, the use of a compound wherein a secbutoxy group and a hydroxy group are coordinated with a copper atom gives a superconductor composed of flat particles having a broad C plane. The dimensional ratio defined by l/d is at least 6.7 in the case of the 124-type or is at least 8.4 in the case of the 123-type. It shows a superconducting property at a liquid nitrogen temperature. This superconductor shows a higher critical current density than one obtained by a sintering method.
