摘要：
This paper present a frequency reconfigurable antenna with metasurface. This antenna consisted of two substrates with the thickness of 1mm. Metasurface with tunable capacitors is placed on the top layer, while the microstrip feeding line and the ground plane are printed below the metasurface. The working frequencies of the proposed antenna are controlled by a single DC voltage applied on the varactors. By altering the capacity of the varactors, the working frequency of the proposed antenna can be shifted from 2.43 GHz to 3.31 GHz. Furthermore, the antenna maintains broadside radiation and has more than 5 dBi gain in all the operating bands.
