16-3 反射板付き6Lポリループアンテナの指向特性

抄録

This paper describes radiation patterns of ladder and hexagonal type 6L-polyloop antennas with finite reflector which we have measured. The polyloop antenna has a structure of directly stacked two "Wavelength Circumference Loop Antenna" or more. We have obtained good results from the ladder type antenna. The half-power beam width of vertical radiation patterns are 33°-42°throughout the band-width which is 30% of it's center frequency.
