Abstract

PURPOSE:To remove transient distortion induced to a feed antenna by making a changeover at a neutral point constants of upper and lower elements of linear dipole antennas constituting a parasitic antenna are balanced including a load. CONSTITUTION:Centering on feed antennas 01 and 02 composed of linear dipoles, parasitic antennas 31 and 32, and 71 and 72 composed of linear dipoles are circularly arranged at even intervals. To both upper and lower antenna elements of each parasitic antenna, one terminal of each halved non-reflective load impedance Za and that of each halved load impedance Zb as a wave director are connected and the other terminals are connected to switches S3 and S7, which are driven to make alternations in sequence according to a fixed program.
