Abstract

PURPOSE:To realize the miniaturization and the reduction of the amplitude fluctuation of the radial pattern for the antenna incorporating the loop reflector by using the blocking bushings as the reflectors. CONSTITUTION:Four units of half-wavelength dipole antennas 1a-1d are provided on the circumference on the same plane and equidistantly, and blocking bushings 5a-5b are provided at the feeding part into a cross form. Thus the blocking bushings function as the reflectors of the dipole antennas. In such way, the diameter of the circle connecting the feeding points features the half-wavelength to realize the miniaturization and the reduction of the amplitude fluctuation of the radial pattern.
