Summary :

The current distribution along a square spiral arm is determined by using Mei's integral equation. The data concerning radiation pattern, power gain, axial ratio and input impedance are presented with good agreement between theoretical and experimental results over a frequency range of 3 to 7 GHz. It is revealed that similar decay in the current distribution, which is necessary to keep wide-band characteristics of the radiation, is obtained in spite of the change of frequency. The data show that the input impedance is nearly a pure resistance, and that, when the radiation pattern in the spiral plane becomes almost omnidirectional, phase of the radiation field varies linearly with the change of the azimuth.
