Characteristics of 5-element right-hand circularly polarized ring loop antenna

The ring loop antenna to which the circumference length parallel supplied loop antenna element of about one wavelength in the previous paper was described. This paper described the antenna which constituted the circularly polarized wave characteristics for experimental use, which verifies the digital broadcasting system. The digital broadcasting system using the airship enables the fixed point to stay in ground station described the condition necessary for generating the circularly polarized wave.
