Description
まず、第1欄にて、用語の定義を行う。
各図において、L軸、W軸およびT軸は互いに直交しており、回路基板1,5における長さ方向、幅方向および厚さ方向を示す。なお、長さ方向、幅方向および厚さ方向は、必要に応じて、縦方向、横方向および上下方向という場合がある。また、長さ方向は第一方向または第三方向の例示であり、高さ方向は第二方向の例示である。
以下の第2欄では、図1〜図5を参照して、本開示の回路基板1に本件発明者が至った経緯について説明する。
上記考察の結果、本件発明者は、図1、図2Aおよび図6に示すような回路基板1を想到するに至った。以下の第3欄では、これら図面に加え、図7〜図9を参照して、本開示の回路基板1を詳説する。
また、第二給電線路19もまた層間に設けられても良い。
本件発明者は、上記構造の回路基板1に対しても三次元電磁界解析を行った。三次元電磁界解析の条件は、第2欄に記載と同様である。
上記の通り、本開示の回路基板1は、複数の放射素子15に近接し、L軸方向に延在する第一給電線路13をまず備える。また、回路基板1は、T軸方向に延在し、第一給電線路13のL軸方向におけるランドL1と、自身の一方端にて接続される第一接続導体17を備える。回路基板1はさらに、W軸方向に延在し、第一接続導体17の他方端(ランドL5)と接続される第一線路部191と、第一線路部191から分岐し、かつL軸方向側から他方端(ランドL5)と接続する第二線路部193を有する第二給電線路19を備える。この構成により、使用周波数帯付近の広帯域にわたって第一供給線路13の部分13a,13bに分配される電力差を抑制することが可能となると共に、導波管を使う必要が無くなるため、安価に構成可能な回路基板1を提供することが出来る。
