Description
図1では第3放射体104は第2放射体102と同一の構造を有する。もちろん、第3放射体104は第1放射体100及び第2放射体102と異なる構造を有することもできる。このような第3放射体104の構造は具現しようとする周波数帯域に応じて適宜設計することができる。
1つの放射体104のみを周波数帯域のために共有して用いた第1実施例と異なり、本実施例では複数の第3放射体204を周波数帯域のために共有して用いる。
上記放射体300、302、304a及び304bに電力を供給する方法は第2実施例と類似しているため、説明を省略する。
他の実施例と異なり、第2放射体502は独立して第2周波数帯域を具現することもでき、第1放射体500と共に第1周波数帯域を具現することもできる。即ち、全ての第2放射体502を第1周波数帯域のために共有することができる。
102、202、302、404、502 第2放射体
104、204、304a、304b、406 第3放射体
106、206、306、504 第1フェーズシフタ
108、208、308、506 第2フェーズシフタ
