Abstract

PURPOSE:To give a rotating directivity by arranging antennas, which function as wave directors or reflectors, around a vertical antenna and switching and scanning them successively. CONSTITUTION:Parasitic vertical antennas 1-6 are arranged around fed vertical antenna O. Load impedance Za or Zb is connected to parasitic antennas, and the load impedance is selectively grounded by switches S1-S6. In case of Za grounded, the antenna operates as a reflector; and in case of Zb grounded, the antenna operates as a wave director. An ideal directivity can be obtained if halves of antennas 1-6 operate as wave directors and reflectors respectively, and a rotating directivity can be obtained by switching successively switches S1-S6.
