Abstract
Description
本発明は、現在広く利用されている携帯電話機に取り付けられている２箇のアンテナ（ホイップアンテナ、内蔵アンテナ）の中の内蔵アンテナの製造方法に関するものである。 The present invention relates to a method for manufacturing a built-in antenna among two antennas (whipped antennas, built-in antennas) attached to mobile phones that are widely used at present.
従来、携帯電話に取り付けられている２箇のアンテナ（ホイップアンテナ、内蔵アンテナ）は両者の何れか強く受信した方のアンテナを自動的に選択して使用されるようになっていて、内蔵アンテナは図２に示したようにプレス加工、又はエッチング加工によって成形されたエレメントを高誘電率材である液晶ポリマーやＰＰＳ等のモールド樹脂の一面に埋め込むように張設することによって一体成形されていた。 Conventionally, two antennas (whipped antennas and built-in antennas) attached to a mobile phone are automatically used to select whichever antenna is stronger. As shown in FIG. 2, the element formed by pressing or etching is integrally formed by stretching so as to be embedded in one surface of a mold resin such as a liquid crystal polymer or PPS which is a high dielectric constant material.
しかし、このような従来の内蔵アンテナには次のような欠点があった。
液晶ポリマー、ＰＰＳ等の高誘電率材料を利用したモールド樹脂は極めて高価なものであるため、内蔵アンテナの価格が高くなり、見込み生産によって在庫させておくことが困難である上、一体成型のため生産能力にも問題があった。
従って、注文を受けてから製造するため急場の受注に間に合わず、流通業界に少なからず支障をきたしていた。
本発明は機能性フィルムを使って予め成形されたエレメントをラミネート工法によって被覆することにより、内蔵アンテナを安価に大量に製造できる製造方法を提供することを目的とする。However, such a conventional built-in antenna has the following drawbacks.
Mold resin using high dielectric constant materials such as liquid crystal polymer and PPS is extremely expensive, so the price of the built-in antenna becomes high, and it is difficult to stock it by prospective production. There was also a problem with production capacity.
Therefore, since the production is performed after receiving the order, it is not in time for the order received in the urgent stage, which has caused a considerable hindrance to the distribution industry.
An object of this invention is to provide the manufacturing method which can manufacture a built-in antenna in large quantities cheaply by coat | covering the element previously shape | molded using the functional film by the lamination method.
上記目的を達成するため本発明はプレス加工又はエッチングによって成形された薄い金属板のエレメント３全体を薄い機能性フィルム材１でラミネート工法によって被覆する方法で製造するものである。
又、薄い機能性フィルムで被覆されたエレメントを金型等で加圧成形し、立体構造に製造するものである。In order to achieve the above object, the present invention is manufactured by a method in which the entire thin
In addition, an element covered with a thin functional film is pressure-molded with a mold or the like to produce a three-dimensional structure.
上記の方法によって製造される内蔵アンテナには次のような効果がある。
液晶ポリマーやＰＰＳ等の高価な高誘電率材料の使用を避け、ＰＥＴ、ＰＰ、ポリイミドのような安価で機能性に優れたフィルム材を使用しているので、大量生産による在庫も可能になり、低価格の内蔵アンテナが提供できる。
機能性フィルム材を使ってラミネート工法、両面接着工法等によってエレメントが密封されるので、エレメントに錆が出たり、変質したりすることがなく、常に一定の性能が保たれている。The built-in antenna manufactured by the above method has the following effects.
Avoiding the use of expensive high-permittivity materials such as liquid crystal polymer and PPS, and using inexpensive and highly functional film materials such as PET, PP, and polyimide, so inventory by mass production is also possible. A low-cost built-in antenna can be provided.
Since the element is sealed using a functional film material by a laminating method, a double-sided adhesive method, etc., the element is not rusted or deteriorated, and constant performance is always maintained.
以下、本発明の実施の形態について説明する。
図１は本発明のラミネート工法によって製造される内蔵アンテナの平面図とＩ−Ｉ断面図で、図２は従来の内蔵アンテナの平面図とＩＩ−ＩＩ断面図で、図３は加圧成形により立体構造とした内蔵アンテナの断面図で、図中の符号Ａは内蔵アンテナを示す。Embodiments of the present invention will be described below.
FIG. 1 is a plan view and II cross-sectional view of a built-in antenna manufactured by the laminating method of the present invention, FIG. 2 is a plan view and II-II cross-sectional view of a conventional built-in antenna, and FIG. It is sectional drawing of the internal antenna made into the three-dimensional structure, and the code | symbol A in a figure shows an internal antenna.
従来の内蔵アンテナは図２に示すように液晶ポリマー、ＰＰＳ等の高価なモールド樹脂板の一面に一体成形するか、接着剤２を介して接着することによって製造されていたが、本発明に於てはプレス加工又はエッチング加工によって成形された動電率の高い薄い金属板のエレメント３全体を薄い機能性フィルム材１でラミネート工法によって被覆する。 As shown in FIG. 2, the conventional built-in antenna is manufactured by integrally molding on one surface of an expensive mold resin plate such as liquid crystal polymer or PPS, or by bonding with an
本発明のもう一つの製造方法として、図３に示したように図１の内蔵アンテナを金型で加圧成形し、立体構造にする。
又、図３に示した立体構造の内蔵アンテナであっても本発明による機能性フィルムでのラミネート工法で大量に安価に提供できる。As another manufacturing method of the present invention, as shown in FIG. 3, the built-in antenna of FIG. 1 is pressure-molded with a mold to form a three-dimensional structure.
Further, even the three-dimensional built-in antenna shown in FIG. 3 can be provided in a large amount at a low cost by the laminating method using the functional film according to the present invention.
