摘要： A miniature chip antenna suitable for use in low-frequency-band mobile communications is disclosed. The chip antenna has a rectangular-prism-shaped base member provided with a mounting surface. Disposed within the base member is a conductor spirally wound along the height of the base member. The base member is formed from e.g., ferrite comprising Ni--Zn having a relative magnetic permeability of 7. The conductor is made from a metal comprising, e.g., Cu, Ni, Ag, Pd, Pt, or Au, and is formed by printing, depositing, laminating or plating. The base member and the conductor are then integrally sintered. A conductor having a rectangular cross section and spirally wound along the height of the base member is thus formed within the base member.

摘要： A chip antenna in which desired antenna characteristics can be obtained without restricting the type of at least one of a dielectric material and a magnetic material used for a base member of the antenna, as well as the type of metal material used for a conductor, or without limiting the sintering conditions of the above-described materials. The chip antenna includes a rectangular-prism-shaped base member having a mounting surface. A conductor, e.g. silver, is spirally wound inside the base member. A feeding terminal is formed over surfaces of the base member so as to feed power to the conductor. One end of the conductor is extended to a surface of the base member to form a feeding section, which is connected to the feeding terminal. The other end of the conductor serves as a free end within the base member. The base member is produced by laminating mixture layers made from a mixture of glass essentially consisting of borosilicate having a softening point of approximately 700.degree. C. and ceramic (relative dielectric constant: 60) essentially consisting of barium oxide, neodymium oxide and titanium oxide having a sintering temperature of approximately 1300.degree. C.

摘要： An antenna apparatus which exhibits excellent mechanical strength and which is protected from heat and moisture, and also which is mountable on a printed wiring board with the provision of a clearance between the apparatus and the board, free from deformation caused by a warp of the board. The antenna apparatus has a rectangular-prism shaped substrate. A feeding terminal and a fixing terminal are disposed at the respective end surfaces in the longitudinal direction of the substrate. Metal strips serving as support terminals are soldered at the respective first ends to the feeding terminal and the fixing terminal, respectively. A coating material formed of a non-metallic material, such as glass, resin or the like, is applied to the surface of the substrate by way of coating, dipping or other method. A coating layer is thus formed on the substrate in a state in which the respective second ends of the metal strips project from the substrate.

摘要： A helical antenna is provided in which a predetermined resonance frequency can be determined at the design stage. The helical antenna includes a conductor which is formed from copper or a copper alloy inside a base in the shape of a rectangular parallelopiped formed from a dielectric material having barium oxide, aluminum oxide and silica as main constituents and which is wound in a helical shape along the length of the base. In such a case, the resonance frequency f0 of the helical antenna and the inductance components L of the conductor satisfy the relationship: ln (L)=A0+A1.times.ln (f0), where ln is a natural logarithm, and A0 and A1 are constants. One end of the conductor is extended onto the surface of the base and forms a power feeding terminal connected to a power feeding terminal formed on the surface of the base for applying a voltage to the conductor, and the other end thereof forms a free end inside the base.
