Slotted Y-shaped millimeter wave reconfigurable antenna for 5G applications

This paper presents the implementation of Millimeter wave (MMW) reconfigurable antenna in a real word environment. Wide bandwidth feature of these waves is the next generation 5G networks. Coplanar waveguide (CPW) feeding technique is used to achieve re-configurability, slotted Y-shaped antenna. The proposed antenna model is incorporated by two variable resistors, which helped in varying of resonant frequency around 26-29 GHz to achieve 10 dB return loss. A comparative analysis is observed among Gain, Directivity and Radiation efficiency pattern of variable resistance. Furthermore, CPW fed technique is compared with Grounded coplanar waveguide (GCPW) for better efficiency and S
