Abstract :
The radiation characteristics of an axial-mode zigzag antenna are evaluated on the basis of the numerically determined current distribution. It is revealed that the frequency at which the maximum gain is obtained decreases as the number of zigzag cells is increased, and that an antenna of two zigzag cells has a high power gain of about 11 dB with a bandwidth of about 11%, although the number of zigzag cells is extremely small.
