A novel design for a beam‐switching antenna based on a new reconfigurable frequency selective surface (FSS) is presented at 2.1 GHz operating frequency. The antenna system consists of an omnidirectional antenna and a cylindrical FSS for controlling its radiation pattern characteristics. The discontinuous split‐ring resonator (SRR) cross‐shape FSS is composed of 12 FSS unit cells with 4 active elements in each one. To reconfigure the radiation pattern of the antenna, a PIN‐diode is specifically placed in the discontinuity of the FSS hybrid element for its switching functions. The antenna radiation sector is determined by the off‐state diodes. This design is used to realise a beam‐switching active antenna covering all azimuth angles. The measurement results are in line with the simulation and confirm the proposed configuration of the antenna. The measurement of the proposed design at the operating frequency resulted in a gain of 8.1 dBi. This antenna can be used in the base station of the wireless communication systems.
