【発明の実施の形態】 DETAILED DESCRIPTION OF THE INVENTION
以下、本発明の詳細について、実施例を示す図面に基づいて説明する。 Hereinafter, details of the present invention will be described with reference to the drawings showing an embodiment. 図1は本発明の標準電波を受信するための表面実装アンテナの1実施例を示す斜視図であり、図2は図1に示す表面実装アンテナの断面図、図3(a)及び(b)は図1に示す表面実装アンテナの結線図、図4は本発明の標準電波を受信するための表面実装アンテナの他の実施例を示す平面図である。 Figure 1 is a perspective view showing one embodiment of a surface mount antenna for receiving the standard radio wave of the present invention, FIG. 2 is a sectional view of a surface mount antenna shown in FIG. 1, FIG. 3 (a) and (b) the connection diagram of the surface mount antenna shown in FIG. 1, FIG. 4 is a plan view showing another embodiment of a surface mount antenna for receiving the standard radio wave of the present invention.
【0010】 [0010]
図1及び図2に示すように、本発明の標準電波を受信するための表面実装アンテナ1には、中央に基台2が配置されており、この基台2から放射状に形成された複数個(図示は4個)のコア3(図2参照)が突出して配置されている。 As shown in FIGS. 1 and 2, a plurality in the surface mount antenna 1 for receiving a standard radio wave of the present invention, the central and base 2 is disposed, which is formed radially from the base 2 (shown four) cores 3 (see FIG. 2) are arranged to protrude. そして、それぞれのコア3の先端には、基台2と同じ高さに形成されたフランジ4が配置されており、このコア3の外周には、コイル5a、5b、5c、5dが巻回されている。 Then, the tip of each core 3, a flange 4 formed at the same height as the base 2 is disposed on the outer periphery of the core 3, the coil 5a, 5b, 5c, 5d is wound ing.
【0011】 [0011]
ここで、基台2と複数個のフランジ4とは必ずしも同じ高さにする必要はないが、同じ高さにすることによって、実装工程において表面実装アンテナ1を供給する際に、表面実装アンテナ1を安定して縦に積み上げることが可能となり、表面実装アンテナ1を回路基板(図示しない)に実装する実装工程において、供給装置から実装装置に容易に供給することができるので、実装工程が容易になり、実装工程を含めた全体としてより安価な表面実装アンテナを提供することができる。 Here, when need not necessarily be the same height as the base 2 and a plurality of flange 4, by the same height, to supply the surface mount antenna 1 in the mounting step, the surface mount antenna 1 stable it is possible to stack vertically, in the mounting step of mounting a surface mount antenna 1 to the circuit board (not shown), it is possible to easily supplied to the mounting device from the supply device, the mounting process is easy it is possible to provide a less expensive surface mounting antenna as a whole, including the mounting process. もし、基台2と複数個のフランジ4とを同じ高さとすることができないときには、複数個のフランジ4を同じ高さにして、基台2をやや低く形成すれば、同じ高さにしたときとほぼ同様の作用、効果を得ることができる。 If, when it is not possible to the base 2 and a plurality of flange 4 to the same height, and a plurality of flange 4 to the same height, if slightly low form base 2, when at the same height If it is possible to obtain substantially the same operations and effects.

そして、基台2の上面に形成された凹部2aの表面には、コイル5a、5b、5c、5dのリード線6a、6b、6c、6dを相互に接続するコイル接続端子7a及び7bが配置されている。 Then, the base 2 of the surface of the recess 2a formed on the upper surface, the coil 5a, 5b, 5c, 5d of lead 6a, 6b, 6c, the coil connection terminals 7a and 7b connecting 6d each other are arranged ing. この実施例における表面実装アンテナ1は、図3(a)に示すコイル5の結線を行う場合を示したものであって、基台2に形成された凹部2aにおいて、コイル接続端子7aの上にコイル接続端子7bが直交して配置されており、コイル接続端子7aと7bとの間は絶縁されている。 Surface mount antenna 1 of the embodiment, merely indicate a case in which the coil connection 5 shown in FIG. 3 (a), in the recess 2a formed in the base 2, on the coil connection terminals 7a coil connection terminals 7b and is arranged perpendicularly, between the coil connection terminals 7a and 7b are insulated. したがって、この接続のコイルは、独立した2個のコイルを直交して配置していることとなる。 Thus, the coil of this connection, so that the are arranged orthogonally independent two coils.
【0013】 [0013]
この直交して配置された2個のコイルは、互いに独立したコイルとなり、従来技術において棒状の表面実装アンテナ20を相互に直交して2個配置したものと同様の効果を得ることができるので、従来技術における2個の表面実装アンテナ20に代えて1個の表面実装アンテナ1を実装すれば足りるので、小型化して省スペースを図るとともに、アンテナの指向性を改善し、かつ、実装工程を含めた全体としてより安価な表面実装アンテナを提供することができる。 The orthogonally two coils arranged becomes a coil independent of each other, it is possible to obtain the same effect as that perpendicular to rod-shaped surface mount antenna 20 to each other are arranged two in the prior art, since it is sufficient to implement the surface mount antenna 1 1 in place of the two surface-mount antenna 20 in the prior art, and compact while achieving space saving, it improves the directivity of the antenna, and including mounting process as a whole it is possible to provide a less expensive surface mounting antenna.
【0014】 [0014]
一方、図3(b)に示すコイル5の結線では、四方にコイル5が突出した表面実装アンテナとなるので、1個の表面実装アンテナでありながら、どのような方向からの電波にも対応することが可能となり、アンテナの指向性が改善されて、携帯機器の姿勢によって感度が変動することの少ない表面実装アンテナとすることができるとともに、小型化して省スペースを図るとともに、実装工程を含めた全体としてより安価な表面実装アンテナを提供することができる。 On the other hand, in the connection of the coil 5 shown in FIG. 3 (b), since the coil 5 in the four directions the surface mount antenna protruding, yet one surface mount antenna, corresponding to radio waves from any direction it becomes possible, directivity of the antenna is improved, it is possible to less surface mount antenna of the sensitivity varies depending on the posture of the mobile device, with is downsized reduce the space, including the mounting process it is possible to provide a less expensive surface mounting antenna as a whole.

図4は、本発明の他の実施例を示すものである。 Figure 4 shows another embodiment of the present invention. この実施例における表面実装アンテナ11は、中央の基台12から3個のコア13が放射状に突出して配置されたものであって、それぞれのコア13の先端に、基台12と同じ高さに形成されたフランジ14が配置されており、コア13の外周には、同様にコイル15が巻回されている。 Surface mount antenna 11 in this embodiment, three cores 13 from the center of the base 12 be one that is arranged to project radially, the tip of each core 13, the same height as the base 12 flange 14 formed are disposed on the outer periphery of the core 13, likewise coil 15 is wound. そして、基台12の上面に形成された凹部12aの表面には、コイル15のリード線16を相互に接続するコイル接続端子17が配置されている。 On the surface of the concave portion 12a formed on the upper surface of the base 12, the coil connecting terminal 17 for connecting the lead wire 16 of the coil 15 to each other are arranged. そして、図4には示されていないが、表面実装アンテナ1と同様に、下面に接続用電極や固定用電極が配置されているが、重複するので、ここでは詳細な説明は省略する。 Then, although not shown in FIG. 4, like the surface mount antenna 1, but the connection electrode and the fixed electrode on the lower surface are arranged, so overlapping, and a detailed description thereof will be omitted.
【0018】 [0018]
この実施例の表面実装アンテナ11は、このように構成されているので、図3(b)に示すコイル5の結線を行った表面実装アンテナ1と全く同様の表面実装アンテナとして使用することができ、表面実装アンテナを小型化して省スペースを図るとともに、アンテナの指向性が改善されて、携帯機器の姿勢によって感度が変動することの少なく、かつ、小型化して省スペースを図るとともに、実装工程を含めた全体としてより安価な表面実装アンテナを提供することができる。 Surface mount antenna 11 of this embodiment, which is configured in this manner, can be used as exactly as surface mount antenna and a surface mount antenna 1 performing the connection of the coil 5 shown in FIG. 3 (b) the surface mount antenna with reduce the space is downsized, the directivity of the antenna is improved, less of the sensitivity varies depending on the posture of the portable device, and, together with miniaturized reduce the space, the mounting process it is possible to provide a less expensive surface mounting antenna as a whole, including.
