摘要:
A C-band circularly polarized reconfigurable reflectarray using electromechanical actuators is presented. Circular rings as unit cell elements enable full 360 degree phase adjustment using variable rotation technique. The performance of the reflectarray in near field focusing is evaluated. A near field focusing gain of 18.5dB and depth of focus (DoF) of 1.76. is obtained. Also a locally plane wavefront is observed around the focal point region.
