Frequency Reconfigurable patch antenna for millimeter wave applications

Abstract

The presented work is a "Y" slotted mm-wave reconfigurable patch antenna, suitable for radar, satellite communications, 5G generation wireless network and millimeter wave energy harvesting. The frequency reconfigurability is achieved using 2 PIN diodes integrated into the radiating element of the antenna. Four frequencies are produced using our proposed antenna, which is respectively 49.84GHz, 31.65GHz, 31,4GHz and 45,45GHz, showing strong performance in term of return loss, bandwidth, directivity, and VSWR. The proposed antenna is designed using an electromagnetic simulator based on finite element method (FEM) HFSSv16 and compared using CSTv18 microwave studio based on Finite integration technique (FIT).
