摘要： A downsized chip antenna having a large bandwidth ratio is disclosed. The chip antenna has a rectangular prism-shaped base member providing a mounting surface. A conductor is formed inside the base member in such a manner that it is spirally wound around a winding axis, for example, a winding axis parallel to the mounting surface, i.e., in the longitudinal direction of the base member. One end of the conductor is extended to a surface of the base member to form a feeding section, which is connected to a feeding terminal, disposed over the surfaces of the base member to apply voltage to the conductor. In one embodiment, the other end of the conductor is connected to a midway portion of the conductor within the base member, thereby forming a loop in said conductor.

摘要： A method of producing a band-pass filter includes selecting the shape of a metallic film and the connection points of input-output coupling circuits such that first and second resonance modes are generated in a metallic film provided on a dielectric substrate. At least a portion of the resonance current or the resonance electric field in at least one of the resonance modes is made discontinuous such that the first and second resonance modes are coupled.

摘要： A band-pass filter includes a metal film provided on a dielectric body. The shape and size of the metal film and the coupling points of input-output coupling circuits are selected such that first and second resonance modes are generated. The metal film has protruding portions or concavities provided thereon such that resonance electric field strength in the first or second resonance mode is controlled to couple the first and second resonance modes to each other.

摘要： A dual mode band pass filter is constructed to be very compact and such that the coupling strength and bandwidth can be easily and widely adjusted while maintaining sufficient freedom of design. A metal film for forming a resonator is arranged on a first main surface of a dielectric body or at a certain height in the dielectric body. At least one ground electrode is arranged such that the ground electrode is opposed to the metal film via the dielectric body. The metal film is connected to input/output coupling circuits. In the region where the metal film is opposed to the ground electrode, two portions are partially provided. Each of these two portions has a relative permittivity that is different from the relative permittivity of the remaining portion, in order to couple two resonance modes.
