A built-in correction method of the phase distribution of a phased array antenna

Ryuji Ishii; Kuniaki Shiramatsu; Tetsuo Haruyama; Nobutake Orime; Takashi Katagi

A correction method for the phase distribution of a phased array antenna by the REV (rotated element electric field vector) method using pickup antennas placed at thinned element positions was proposed and tested. The effectiveness of this method for reforming a beam is verified.<<ETX>>

Conformal array antenna with digital beam forming network

Tetsuo Haruyama; Nakato Kojima; Isamu Chiba; Yoshimasa Oh-hashi; Nobutake Orime; Takashi Katagi

A spherical conformal array antenna that has 64 elements with a digital beam-forming network has been tested. Low sidelobe pattern synthesis of a conformal array antenna using the network was demonstrated. Multiple beam forming with maximum gain was also considered.<<ETX>>
