摘要

In this paper, a method of designing a Vivaldi type phased array antenna (PAA) which operates at S-band (2.8–3.3 GHz) is presented. The presented antenna uses broadside coupled split ring resonators (BC-SRRs) for high isolation, wide field of view, and good active S-parameter characteristics. As an example, we design a 1 × 8 array antenna with various BC-SRR structures using theory and EM simulations. The antenna is fabricated and measured to verify the design. With the BC-SRR implemented between the two radiating elements, the isolation is shown to be enhanced by 6 dB, up to 23 dB. The scan angle is shown to be within ±53° based on a ?10 dB active reflection coefficient. The operation of the scan angle is possible within ±60° with a little larger reflection coefficient (?7 dB to ?8 dB). The proposed design with BC-SRRs is expected to be useful for PAA applications.
