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 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： An antenna apparatus having a predetermined impedance is provided. The apparatus has a chip antenna including a conductor and a mounting board on which the antenna is mounted. A ground pattern and a microstrip line are formed on the board. A feeding terminal for applying a voltage to the conductor is deposited on the surface of the antenna. Solder may be used to connect the feeding terminal of the antenna to the microstrip line formed on the board. A capacitance generating device, e.g., a dielectric resin or capacitor is disposed between the microstrip line connected to the feeding terminal of the antenna and the ground pattern. A capacitance is thus generated between the microstrip line and the ground pattern thereby enabling regulation of the antenna apparatus impedance and bandwidth.
