Abstract :
The transmission line periodically loaded with split-ring resonators (SRR) has been investigated. The phase delay of the wave in the considered transmission line is equal to zero at the frequency slightly above the SRR resonance. This effect was used for designing the near-field loop antenna providing the uniform current distribution along the loop. A comparison of the proposed design and the conventional loop antenna was made.
