査を行う電子走査アンテナにおいて、ビーム走査
のための位相を制御する第１の制御器と、和と差
の放射パターン形成のための位相を制御する第２
の制御器とを設け、第１の制御器による位相と第
２の制御器による位相との合計値を上記位相器に
与えることを特徴とする電子走査アンテナ。 The device includes a plurality of radiating elements arranged on a curved surface, a phase shifter connected to the radiating element, and a feeding circuit connected to the phase shifter, and has a sum radiation pattern and a difference radiation pattern. In an electronic scanning antenna that performs beam scanning electronically, a first controller controls the phase for beam scanning, and a second controller controls the phase for forming a sum and difference radiation pattern.
An electronic scanning antenna comprising: a controller; and a total value of a phase determined by the first controller and a phase determined by the second controller is provided to the phase shifter.
