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.

Poly Loop Antenna is a new type of UHF broadcasting antenna derived from both "Ladder-Type Loop Antenna" and "Tetracene-Type Antenna" which we published before. This antenna has a structure of directry stacked two "Wavelength Circumference Loop Antenna" or more. The folloing explanations are how poly loop antenna works.

In this paper we will show you regarding vertical and horizontal radiation patterns of 4L-polyloop antennas with finete reflector which we have measured recently. We have obtained good results on the hexagon 4L-polyloop antenna acording to the measured data. This antenna has a structure of directly stacked twin "Wavelength Circumference Loop Antenna"
