摘要： An antenna is formed by attaching a metallic chassis to a dielectric base plate on which are formed an input electrode, a connector electrode and grounding areas. The metallic chassis has a planar part serving as its radiating part and attachment parts formed by bending mutually opposite edge parts of this planar part substantially perpendicularly thereto, and the input electrode, the connector electrode and one of the grounding areas are each connected to either of the attachment parts. An antenna unit is formed by mounting the metallic chassis of such an antenna inside an opening formed in a printed circuit board on which are formed a feed electrode and grounding electrodes formed with an edge portion of each abutting this opening and by connecting the input electrode to the feed electrode, and the grounding electrode to one of the grounding areas.

摘要： A matching circuit and an antenna apparatus which, though small-sized, can be used in a radio apparatus which transmits and receives radio waves having a wide range of frequencies. A matching circuit includes an inductance element formed of a chip inductor connected in series with an antenna body, a first capacitance element formed of a trimmer capacitor, and a second capacitance element formed of a chip capacitor, which capacitance elements are connected between respective ends of the inductance element and a ground terminal, and thus in parallel to the antenna body. One end of the inductance element is connected to the power supply terminal of the antenna body, and the other end is connected to a power source for applying a voltage to the antenna body. The first capacitance element is connected between a ground and the connection point of the power supply terminal of the antenna body and the inductance element. The second capacitance element is connected between a ground and the connection point of the inductance element and the power source.

摘要： A resonator having an improved spurious characteristic is provided. The resonator comprises a dielectric substrate having a plurality of strip lines extending longitudinally from the central portion of the upper surface toward the rear surface of the substrate by turning downward along the shorter side surfaces of the substrate such that the strip lines extending from both sides of the upper surface of the substrate are arranged in an alternative fashion with their narrowed top end portions overlapping each other in spaced apart relationships so as to be electromagnetically coupled. The portion of the dielectric substrate sandwiched between the opposing upper and rear portions of each strip line forms a capacitor. Further, a ground electrode is formed at the center of the rear surface of the substrate so as to be connected to the end portions of the strip lines. Input and an output electrode continuous with some of the strip lines, respectively, are also provided on the rear surface of the substrate.
