Characteristics of Broad band 3-Element Ring Loop Antennas
Haruo Kawakami (AG)
Abstract (in Japanese) (See Japanese page) 
(in English) This paper it was the simple structure in order to solve the problem, and the diameter was small, and the miniaturization was possible, and again, it developed ring loop antenna for the terrestrial digital broadcasting of which good VSWR characteristics over all bands in the use frequency band was obtained. Frequency characteristics are almost often equal on electric field and magnetic field plane for the loop antenna that the circumference length arranged loop antenna element of the about one wavelength multi-bay and that it parallel fed electricity for both directionalities and impedance characteristic, and the half-power angle becomes about 80 degrees. This antenna designed in order to match the coaxial cable of 50 Ω, shows 39.7% ( 1.65 times ) and wide-band characteristics, if the frequency band of VSWR=2 or less is under 49.2% ( 1.49 times ) and under 1.2 almost.
