Abstract

Analysis is newly performed for a one-wavelength rectangular loop antenna having an unbalanced feed. This antenna radiates an axial beam in a direction normal to the antenna plane. Subsequently, the axial beam is transformed into a conical beam by taking the loop perimeter to be two wavelengths. It is found that as the aspect ratio is varied, the antenna shows two minima in the axial ratio characteristic, where the rotational senses of the circular polarization are different from each other. Finally, a tilted beam is formed by superimposing the axial and conical beams for a double-loop antenna.
