Abstract
An Archimedean spiral antenna, two arms of which are located above a conducting plane reflector at a small height, is numerically analyzed. Resistive loads are used to reduce standing wave currents on the arms. At the lowest frequency (the antenna height corresponding to one-twentieth the wavelength), the spiral shows a gain of approximately 3 dB with an axial ratio of approximately 4 dB.<>
