Description of the Invention (1) (Technical Field to Which the Invention belongs) The present invention relates to antenna devices used in portable communication equipment and the like. (Prior art) In the past, communication devices such as mobile phones used linear antennas such as helical antennas. However, these devices were installed outside the casing of the communication device. On the one hand, they became a hindrance to miniaturization. The effect on the antenna may cause problems such as damage, deformation, and deterioration of characteristics. In addition, the number of parts must be increased through the installation of coaxial cables or connectors, which is also unsuitable in terms of installation cost. In order to solve the above-mentioned method, there is a proposal in Japanese Patent Laid-Open No. 9-6 4 6 2 7 as shown in FIG. 26. A small antenna that can be surface-mounted on a circuit board is shown in FIG. This antenna uses the technology of a porcelain multilayer substrate to form a spiral antenna inside the porcelain substrate 30. In detail, the conductor 31 is formed in different porcelain layers. The inner through-hole filled conductor 32 is laminated to form a spiral conductor as a whole, and a porcelain layer is laminated to form a porcelain antenna with a spiral radiation conductor inside. A terminal 33 for supplying electricity to the spiral conductor is formed on the end surface of 0. (Problems to be Solved by the Invention) However, in the above-mentioned structure, it is necessary to form a conductor on the porcelain sheet before firing, and then laminate and fire it, so it is necessary to consider the design of firing shrinkage, etc. In order to maintain the shrinkage ratio to a certain level, you must require non-accuracy (please read the note on the back?

When it was invented, it was easy to mass-produce, and the cost was greatly reduced. Furthermore, since the side convex portion or the side concave portion of the conductor is formed as a terminal electrode, it is easy to manufacture a surface-mounted antenna.

(Dupont Corporation Q S — 1 7 1) The following describes the manufacturing process of the antenna device 1 shown in FIG. 1 with reference to FIGS. 2 to 5. First, an alumina substrate 9 as shown in FIG. 2 is prepared. On this alumina-based ® 9, a cut-off line 10 is provided so that the desired size can be divided in a later process. A through-hole 11 is provided at a desired place on the cutting line. In this example, '50 mm x 50 mm, the thickness of 1 mm on the oxidized substrate on the cut-off line 10 is a 5 mm interval in the vertical direction, the horizontal 10 mm interval 'will pass through the hole 11 1 0. 8 0, They are arranged at intervals of 2 mm above the cross-section line in the horizontal direction. Next, conductor patterns 1 2 ′ 1 3 are formed on the upper surface 9 Γ and lower surface 9 2 of the alumina substrate 9 as shown in FIG. 3 (A) and FIG. 3 (B). The forming method is to screen print the conductor paste, and then dry it at 850 ° C. Next, the alumina substrate 9 after the upper and lower conductors are formed is divided into shapes as shown in FIG. 4 along a cut-off line in which a through-hole is formed. In addition, the conductor paste 15 is preliminarily extended to a thickness of 0.2 mm using a squeegee (Singe) or the like, and the conductor paste 15 is impregnated with the convex portion formed by the through hole of the alumina substrate described above, and the conductor is The paste 15 was applied only to the tip of the convex portion, dried, and fired. Finally, as shown in FIG. 5, the antenna unit 1 is obtained by dividing into minimum units by a cut-off line.

The inner wall forms a conductor 5 and the conductors 3, 4, 5 form a spiral conductor. However, the point that all of these conductor layers 3, 4, and 5 constitute a conductor layer that spirally surrounds the base body 2 is the same as that of the antenna device shown in FIG. In this example, the substrate 2 of the antenna device 1 shown in FIG. 6 is the same as the antenna device shown in FIG. 1 in the high frequency band, and the specific permittivity (er) and specific permeability (// r) are stable. Moreover, the lower the loss, the smaller the temperature coefficient (τ f) of the resonance frequency is suitable. In this example, an alumina-based ceramic plate is used (er = 8.5, Q = 1000, r f = 3 8 p p m / ° C at 2 GHz). Conductors with low resistance such as copper, silver, gold, and nickel are appropriate. In this example, silver-platinum paste is used. (Dupont 03--17 1). Next, a manufacturing method of the antenna device 1 shown in FIG. 6 will be described with reference to FIGS. 7 to 7 showing the manufacturing process of the antenna device 1 shown in FIG. 6.

As described above, the antenna with this structure can manufacture a large number of antennas at a time, and the effect of reducing the manufacturing cost is great. In this case, the two embodiments have been described so far. However, any of these embodiments can be re-formed on the conductive layer formed on the alumina substrate before or after the alumina substrate 9 is divided. A layer that is homogeneous to the alumina substrate 9 will have a smaller antenna size for transmitting and receiving antennas in the same wavelength band. Next, the performance of the antenna device manufactured as described above will be described. This example illustrates the antenna device shown in FIG. This antenna device 1 was placed on a substrate for evaluation, such as 2.5 x 50 mm and a thickness of 0 · 8 mm as shown in Fig. 1 1.
