Characteristics of circular loop antenna with parasitic elements

摘要

The circular loop antenna with the circumference of one in wavelength radiates the maximum power to the direction of a loop axis. A concentric loop antenna with the parasitic loop element with the circumference of about four in wavelength makes increase the directive gain. In this paper, it is discussed on the characteristics of a concentric antenna with a parasitic loop and a circular loop antenna with two parasitic linear conductors. The experimental values agree well with the calculated results.
