A Frequency Reconfigurable Flexible Antenna for Multiple Mobile Applications

A compact Co-Planar Waveguide fed frequency reconfigurable antenna is proposed. The antenna consists of a simple structure, with an arrow-shaped radiator and a matching stub to cover complete 5G sub-6 GHz band. The antenna is further connected to a rectangular patch to cover ISM band, while the inverted L shaped stubs are connected to this patch which further lowers the resonating frequency. Three diodes offer five different states of resonance and cover a single band at a time, which minimizes the effect of interference. The antenna is simulated using Electromagnetic solver, High-Frequency Structural Solver (HFSS) and results are compared with those of Microwave CST.
