  • Abstract
    The input impedance of a rectangular spiral antenna is calculated as a function of wire radius. A value close to 60¿ ¿ is obtained when neighbouring filaments are spaced by nearly the equivalent strip width, although the spiral is not exactly self complementary. When the spiral arm is suitably bent the circularly polarised radiation pattern is widened in one principal plane, while maintaining the inherent input impedance and power gain.
