In this work a metasurface able to provide anomalous refraction of a plane wave has been proposed. Unlike other designs, our structure is made of just one type of geometry, what makes the design very simple. Besides, since each element is very transparent in a wide range of frequency, at least in the range 0-6 GHz, the whole metasurface is frequency stable. We have found that the simulated structure provide anomalous refraction from 3 to 4 GHz.
