Abstract
A Radiation reconfigurable antenna is presented for n78 band 5G applications. A planar monopole is combined by a tuning fork and a U shaped strip to form radiating element. A partial ground is maintained at back side. Four metamaterial unit cells are used in this design, two at each side of the radiator to achieve the radiation re-configurability. Comb shaped metamaterial unit cells are placed in a clock wise direction around the antenna and connected to radiator via BAR-64-02V PIN diodes. The proposed reconfigurable antenna operates at 3500MHz for almost all switching conditions. On the basis of the condition of switching diode the antenna radiation pattern is mainly reconfigured into 45o and 135o directions. The antenna’s overall dimensions in X×Y×Z directions are 30mm×26mm×1.57mm. The designed antenna achieved different pattern combinations when diode switching conditions are applied, making it suitable for n78 band 5G applications.
