Abstract
A polarization dependent negative permittivity controlled energy absorber is proposed. The preparatory study includes a unique design of 5G cell phone radiating patch antenna (RPA) centring at Sub-6 Mid-band frequency range from 3.3 to 3.8 GHz. The proposed configuration exhibits the energy absorptance efficiency of the absorber when attached with 5G cell phone RPA, where absorber will protect the human brain from exposure of radio frequency fields in mobile phone applications. In proposed setup, we vary the geometrical parameters as well as the electrical value of lumped inductor element of the energy absorber and obtained stop band blocking window with comparative study to restrict the specific absorption rate and power/energy flow radiating from RPA toward the simulated human's brain. Moreover, the absorber does not significantly creates mismatch losses, nor effects the voltage standing wave ratio of RPA and hence a promising application to avoid the health hazards as well as for the safety compliance of 5G technology.
