Abstract :
We present a novel design of frequency-scanning array antenna which consists of eight antiresonant dipoles fed by balanced microstrip line. Feeding network contains four elongated split-ring resonators (SRRs) placed between dipoles to increase the frequency dependant phase difference between radiating elements. Split-ring resonators are with gap parallel and far from microstrip line that provides better matching in a wider frequency range in comparison to the similar SRRs with gap close to microstrip line. The beam scanning is found to be Δ=36° with frequency variation in the range from 5.7GHz to 6.1GHz and a very flat gain between 12.5 and 13.6dBi.
