Description
なお、給電素子210は、外部の無線信号を受信して給電を行うものであって、基板212、及び基板212の一面にマイクロストリップパターン216の形成されたパターン部214を備える。パターン部214には、軸比帯域幅を増やすために、ウィルキンソン分配器を使用した4つの直接給電点218が形成される。直接給電点218は、給電中心部220から互いに直角方向に放射状に形成され、給電中心部220を原点とする際に、各給電点218の位相が0°、90°、180°及び270°にする。よって、図5によってわかるように、2つの直接給電点218を結ぶ2本の仮想の直線は、中心部220を通りながら互いに直交する。直接給電点218には、電気的信号を放射パッチ240に直接に給電するために、給電点218と放射パッチ240とを電気的に連結した円柱230が形成される。
