Abstract :
An analysis of wave propagation on an infinitely long Yagi array of concentric circular loops is outlined. A dispersion relation is solved numerically for the phase velocity of the wave. The array is found to possess two distinct passbands corresponding to the resonances of the inner and the outer loops, respectively. The theoretically determined phase velocities are compared with experimentally measured values.
