Abstract
Description
図1は特許文献1に示されているアンテナの斜視図である。図1に示すように、表面実装型のアンテナ1は、直方体状の誘電体基体2と、その誘電体基体2に形成されたループ状の放射電極3及び給電電極4とを有している。給電電極4は誘電体基体2の底面2cから側面2bに形成され、その側面2bの横側端縁領域を通って上面2aに向けて形成されている。放射電極3は、給電電極4から長方形状の上面2aの各辺の近傍領域を各辺に沿ってループ状に形成されている。このループ状の放射電極3の開放端3aは給電端部側の張り出し電極部18に所定の間隔を介して対向配置され、開放端3aと給電端部側の張り出し電極との間に容量が生じるように構成されている。
さらに、放射電極の開放端の位置により放射特性が大きな影響を受けるので、高次モード制御用の容量を形成することが、結果的に基本モード及び高次モード双方の放射特性を犠牲にする場合がある。
また、分岐電極により高次モードを制御するため、放射電極の開放端を任意に配置でき、基本モード・高次モード共に放射特性の高い放射電極を構成できる。
図2は第1の実施形態に係るアンテナ及びその実装状態を示す斜視図である。アンテナ41は、誘電体基体21の表面に所定パターンの電極が形成されたものである。誘電体基体21は、誘電体セラミックス材料、又は誘電体セラミックス粉と有機材料とのコンポジット材料が直方体形状に成形されたものである。
なお、この例ではグランド電極上にアンテナ41を実装したが、回路基板31にグランド電極非形成領域を設けて、その領域にアンテナ41を実装するようにしてもよい。
例えば基本モードは放射電極22が1/4波長共振するモードであり、この基本モードでは放射電極22の先端で電圧振幅最大となる電圧が分布する。高次モードは放射電極22が例えば3/4波長共振するモードである。この高次モードでは放射電極22の先端で電圧振幅最大となり、給電端寄りの位置にもう一つの電圧振幅最大の点(腹)が生じ、二つの電圧振幅最大の点の間に電圧振幅が最小の点(節)があるように電圧が分布する。
また、放射電極22の開放端の位置は基本モード・高次モードともに放射特性に影響を与えるが、本発明では、放射電極22の開放端を高次モードの制御に特に用いないので、放射電極22の開放端を任意に配置できる。そのため、基本モード・高次モード共に放射特性の高い放射電極を構成できる。
図3は第2の実施形態に係るアンテナ42及びその実装状態を示す斜視図である。第1の実施形態で図2に示したアンテナ41と異なるのは、放射電極22の形状である。図3に示す例では、誘電体基体21の側面Ss1に形成されている放射電極部22a,22bと、誘電体基体21の上面Stに形成されている放射電極部22c,22d,22e,22fとで放射電極22が構成されている。
このように、放射電極22の開放端は給電端FPの位置に依らずに自由に配置できる。
図4は第3の実施形態に係るアンテナ43及びその実装状態を示す斜視図である。第1の実施形態で図2に示したアンテナ41と異なるのは、誘電体基体21に無給電電極を更に設けた点である。
図5は第4の実施形態に係るアンテナ44及びその実装状態を示す斜視図である。第1の実施形態で図2に示したアンテナ41と異なるのは、分岐電極23の形状である。図5に示す例では、放射電極部22cの給電端付近の分岐点BPから直交方向に分岐した分岐電極23が誘電体基体21の上面Stに形成されている。この分岐電極23の先端と、放射電極22のうち高次モードの最大電圧が生じる点(位置)との間に容量を生じさせている。
