Description
本発明は、携帯電話等の携帯無線機に関し、特に逆Fアンテナを用いた携帯無線機に関する。
The present invention relates to a portable wireless device such as a mobile phone, and more particularly to a portable wireless device using an inverted F antenna.
携帯電話等の携帯無線機に用いられる逆Fアンテナとして、例えば特許文献1や特許文献2で開示されたものがある。特許文献1(発明の名称:板状逆Fアンテナおよび無線通信装置)には、逆Fアンテナを実装する回路基板のグランドパターンの形状を、逆Fアンテナの設置位置に当たる領域を除いた形状とする点が開示されている。特許文献2(発明の名称:アンテナ装置および無線装置)には、2つの放射素子に対する給電を切り替え自在とし、給電を行わない放射素子を接地し、接地した放射素子を、給電した放射素子の地導体とする構成が開示されている。
As an inverted F antenna used for a portable wireless device such as a cellular phone, there are those disclosed in Patent Document 1 and Patent Document 2, for example. In Patent Document 1 (name of invention: plate-like inverted F antenna and wireless communication device), the shape of the ground pattern of the circuit board on which the inverted F antenna is mounted is a shape excluding the area corresponding to the installation position of the inverted F antenna. The point is disclosed. In Patent Document 2 (name of the invention: antenna device and radio device), feeding to two radiating elements is switchable, a radiating element that is not fed is grounded, and the grounded radiating element is grounded to the radiating element that is fed. A configuration as a conductor is disclosed.
図6は、従来の逆Fアンテナの概略構成を示す図である。同図に示すように、逆Fアンテナ20は、放射素子21と回路基板(図示略)のグランドパターン25が平行に配置され、給電部22および短絡部23がグランドパターン25に接続された構成を採る。逆Fアンテナ20では、放射素子21とグランドパターン25との間隔が狭いほど使用可能な周波数帯域が狭くなり、広いと広帯域となる。
FIG. 6 is a diagram showing a schematic configuration of a conventional inverted-F antenna. As shown in the figure, the inverted F antenna 20 has a configuration in which a radiating element 21 and a ground pattern 25 of a circuit board (not shown) are arranged in parallel, and a power feeding section 22 and a short-circuit section 23 are connected to the ground pattern 25. take. In the inverted F antenna 20, the usable frequency band becomes narrower as the distance between the radiating element 21 and the ground pattern 25 becomes narrower, and becomes wider as the distance becomes wider.
図7は、逆Fアンテナ20を内蔵した携帯無線機の内部構造を概略的に示した図である。この場合、逆Fアンテナ20は放射素子21が筐体30の幅方向に平行となる向きに配置されているため、図7では短絡部23のみが見えている。また、放射素子21については、延設方向の端面(即ち開放端の面)21aが見えている。
FIG. 7 is a diagram schematically showing the internal structure of a portable radio having a built-in inverted F antenna 20. In this case, since the inverted F antenna 20 is disposed in a direction in which the radiating element 21 is parallel to the width direction of the housing 30, only the short-circuit portion 23 is visible in FIG. As for the radiating element 21, an end face (that is, an open end face) 21a in the extending direction is visible.
図7において、筐体30内には、逆Fアンテナ20を実装した回路基板(メイン基板)40とキー41との間にメッキシャーシ(またはグランドシールド)42が配置されている。メッキシャーシ(またはグランドシールド)42は、回路基板40にキー41を設ける為とノイズ対策の為に設けられる。前述したグランドパターン25は、回路基板40の逆Fアンテナ20側の面に設けられている。筐体30内にはメイン基板である回路基板40の他にサブ基板である回路基板43も設けられている。
In FIG. 7, a plating chassis (or ground shield) 42 is disposed in the housing 30 between a circuit board (main board) 40 on which the inverted F antenna 20 is mounted and a key 41. The plating chassis (or ground shield) 42 is provided for providing the key 41 on the circuit board 40 and for noise countermeasures. The ground pattern 25 described above is provided on the surface of the circuit board 40 on the inverted F antenna 20 side. In addition to the circuit board 40 that is a main board, a circuit board 43 that is a sub board is also provided in the housing 30.
しかしながら、携帯無線機の薄型化が要望される中にあってメッキシャーシ(またはグランドシールド)42を設けることで、回路基板40と逆Fアンテナ20の放射素子21の間隔を狭くせざるを得なくなり、使用可能な周波数帯域が狭くなるという問題がある。
However, there is a need to reduce the thickness of the portable wireless device, and by providing the plating chassis (or ground shield) 42, the distance between the circuit board 40 and the radiating element 21 of the inverted F antenna 20 has to be reduced. There is a problem that the usable frequency band becomes narrow.
本発明は、係る事情に鑑みてなされたものであり、携帯無線機の薄型化を図りながらも、回路基板と逆Fアンテナの放射素子との間隔を広げて広帯域化を図ることができる携帯無線機を提供することを目的とする。

According to the above configuration, the ground corresponding to from the end of the ground pattern in the extending direction of the antenna element to the open end of the antenna element is used as a conductive member instead of the ground pattern of the circuit board. Since the antenna element is arranged so as to be separated from the antenna element in the thickness direction of the casing, the gap between the antenna element and the ground can be increased by making the most effective use of the thickness of the casing of the portable wireless device. Therefore, it is possible to widen the band by widening the distance between the circuit board and the radiating element of the inverted F antenna while reducing the thickness of the portable wireless device.
上記構成において、前記給電部および前記短絡部は、前記回路基板の一方の端部から前記給電部、前記短絡部の順に、または前記短絡部、前記給電部の順に前記グランドパターンに対応させて配置されている。

グランド板金8は、アンテナ素子6の延設方向におけるグランドパターン7の端部7aからアンテナ素子6の開放端6aまで、筐体2の厚み方向においてアンテナ素子6と離隔するように配置されている。グランド板金8は、アンテナ素子6の延設方向におけるグランドパターン7の端部7aからアンテナ素子6の開放端までに対応するグランドを、回路基板3のグランドパターン7に代ってとるためのものである。このグランド板金8によりアンテナ素子6のグランドとの間の距離を長くとることができ、回路基板3のグランドパターン7を利用する場合と比べて広帯域化が図れる。
The ground metal plate 8 is disposed so as to be separated from the antenna element 6 in the thickness direction of the housing 2 from the end 7 a of the ground pattern 7 in the extending direction of the antenna element 6 to the open end 6 a of the antenna element 6. The ground metal plate 8 is used to replace the ground pattern 7 of the circuit board 3 with a ground corresponding to the end 7 a of the ground pattern 7 in the extending direction of the antenna element 6 and the open end of the antenna element 6. is there. The distance between the ground of the antenna element 6 and the ground of the antenna element 6 can be increased by the ground metal plate 8, and a wider band can be achieved as compared with the case where the ground pattern 7 of the circuit board 3 is used.
図2は、図1の(c)における回路基板3と逆Fアンテナ10とグランド板金8を拡大した図である。同図に示すように、グランド板金8は、2つの板金8a、8bからなり、板金8aは回路基板3に対して垂直方向に回路基板3のグランドパターン7の端部7aに接続され、板金8bは部分8aと直角になる向きで部分8aの先端部分に接続される。板金8aの長さは、板金8bの厚みを加算した長さが回路基板3から筐体2の内面までの長さと略同一になる長さとなる。また、板金8bの長さは、回路基板3のグランドパターン7の端部7aからアンテナ素子6の開放端6aに達する長さとなる。なお、グランド板金8は必ずしも2つの板金8a、8bで構成する必要はなく、一体形成するようにしてよい。
FIG. 2 is an enlarged view of the circuit board 3, the inverted F antenna 10 and the ground metal plate 8 in FIG. As shown in the figure, the ground sheet metal 8 is composed of two sheet metals 8a and 8b.

FIG. 4 is an enlarged view of the upper end portion of the circuit board 3 in FIG.
逆Fアンテナ10の給電点と短絡点には電流が集中するため、給電部4および短絡部5を堅牢な回路基板3で受けることで回路基板3の幅方向に電流を流し、アンテナ素子6の開放端6aをグランド板金8で受けることで、高インピーダンスであるアンテナ素子6の開放端6aを回路基板3のグランドパターン7から距離的に離すことができる。

Since the ground sheet metal 8 is provided so as to be separated from the element 6, it is possible to increase the distance between the antenna element 6 and the ground by making the most effective use of the thickness of the housing 2 of the portable wireless device 1. As compared with the case of using the third ground pattern 7, a wider band can be achieved.
なお、上記実施の形態では、給電部4および短絡部5を回路基板3の長手方向の一方の端部3aから長手方向の他方の端部3b(図1または図3または図4参照)に向けて、短絡部5、給電部4の順に配置したが、逆順で配置しても効果に変わりはなく、回路基板3における回路設計の自由度を上げることができる。

Although the short-circuit portion 5 and the power feeding portion 4 are arranged in this order, the effect is not changed even if they are arranged in the reverse order, and the degree of freedom of circuit design in the circuit board 3 can be increased.
また、上記実施の形態において、逆Fアンテナ10のアンテナ素子6の先端部分に対してグランド板金8を設けることで、グランド板金8の後方にスペースが得られる。このスペースを様々な用途に利用することができる。図5は、当該スペースにストラップホール15を設けた応用例の概略構成を示す断面図である。
