Claims (1)
エレメントを備え、これらのアンテナエレメントで受信
した電波をそれらの一方又は両方を移相した後加算して
所定方向からの電波についての出力のみを送出するよう
にした位相差給電アンテナにおいて、前記両アンテナエ
レメントの給電部間の距離をそれらのエレメント端間の

テナ。Equipped with a pair of Goupole-type antenna elements facing each other at a predetermined distance apart, the radio waves received by these antenna elements are phase-shifted and then added together, and only the output of radio waves from a predetermined direction is sent out. In the phase difference feeding antenna, the distance between the feeding parts of both antenna elements is made smaller than the distance between the ends of those elements.
