Abstract :
A dual-frequency, broadband reflectarray antenna with dual linear polarizations using triple-resonance elements is presented. The phasing element consisting of double square loops and an inner square patch is optimized to simultaneously provide desired phase shifts at the receiving and transmitting frequencies at Ku band. A reflectarray with a square aperture size of 350 mm × 350 mm is designed and analyzed using full-wave simulation software. The simulated results demonstrate that the gains are 30.85 dB at 12.5 GHz and 31.95 dB at 14.25 GHz, respectively, and the aperture efficiency greater than 45% can be achieved within a broad frequency band of 11.9-15.2 GHz.
