Abstract

This paper presents a simple design of linear series-fed frequency scanning antenna arrays with: (a) identical rectangular dipoles and (b) pentagonal dipoles having different impedances to provide enhanced side lobe suppression. Phase shifters are designed as a metamaterial unit cell consisting of split-ring resonators coupled with the parallel microstrip line. Shifter models variations are described and control of phase is demonstrated. Two antenna arrays are manufactured and measured.
