| Abstract: | This paper presents a reconfigurable metamaterial unit cell using crossed arms and its application in designing a wideband beam-scanning circularly polarized (CP) reflectarray (RA) antenna. The unit cell is comprised of two pairs of reconfigurable rotated crossed-arms. One pair is connected by two line strips, and the other pair is connected by two arc-shaped strips. The unit cell is verified with a broad CP reflection bandwidth of 7.7-15.5 GHz. An equivalent circuit is utilized to illustrate its working principle for wide CP reflection bandwidth. Based on this meta material unit cell, a broadband RA antenna was designed, developed, and tested for the initial CP performance verification. A high gain of 26.3 dBic with the maximum aperture efficiency of 58.3 % is obtained for this fabricated RA antenna. In addition, a broad CP bandwidth (from 7.6 GHz to 15.9 GHz) for axial ratio <3 dB is achieved for the high gain unidirectional CP radiation. |
