Publication number: 20230361463Abstract: A method for calibrating a phased array antenna is provided. The phased array antenna includes multiple transmission modules each including a phase shifter that changes a phase of a high frequency signal output from a signal source, an amplifier that amplifies an amplitude of the high frequency signal, and a transmission antenna that converts the high frequency signal into a radio wave, and a reception module including a reception antenna. The method includes a step of receiving, by the reception antenna, a reflected wave that is a radio wave transmitted from the transmission antenna of each of the multiple transmission modules and reflected outside the phased array antenna, and a step of adjusting the phase shifter and the amplifier of each of the multiple transmission modules based on an amplitude and a phase of the reflected wave received.Type: ApplicationFiled: September 30, 2020Publication date: November 9, 2023Applicant: Mitsubishi Electric CorporationInventors: Takashi MARUYAMA, Shigeo UDAGAWA, Mitsuru KIRITA, Tai TANAKA, Ryotaro OHASHI
