摘要：
A frequency-reconfigurable slot antenna designed using metasurface (MS) is proposed and studied. The proposed antenna is composed of a simple circular slot antenna and a circular MS with the same diameter of 50 mm and implemented using planar technology. The MS is placed directly atop the slot antenna, making the proposed antenna very compact. The MS consists of rectangular-loop unit cells placed periodically in the vertical and horizontal directions. Frequency reconfigurability of the antenna is achieved by rotating the MS around the center with respect to the slot antenna. The antenna with MS is studied, designed and optimized to operate at around 3 GHz using computer simulation. The simulated performances in terms of frequency reconfigurability and radiation pattern are presented.
