Abstract
Taking the spiral circumference, C, of a single wire spiral antenna as 2.3 .lambda. (.lambda. being the wavelength at the operating frequency), for example, the beam radiated from an axis Z perpendicular to the antenna surface is tilted. The beam tilt angle changes with the spiral circumference, C, and the spiral circumference, C, is set to between 2 .lambda. and 3 .lambda..
