Abstract:

The slow wave antenna is considered in this report as a special case of a vertical monopole with a current of arbitrary phase velocity. The electric field, radiation resistance, and power gain are discussed in general as functions of the antenna phase velocity. Particular attention is given to the special cases of one-quarter and three-quarter wavelength antennas. The limiting values of the parameters as the phase velocity along the antenna approaches zero are discussed. Conclusions are reached concerning the maximum expected gain of a slow wave antenna.
