Co-planar proximity fed nanofilm microstrip antenna: Modeling and simulation analysis

This paper presents modeling and simulation characterization of a co-planar proximity fed patch antenna that utilizes copper nanofilm (thickness: 1-100 nm) as a radiating element using IE3D simulation software. On a 1.6 mm height FR4 substrate, the proposed antenna resonates at 6.2 GHz and 9.8 GHz, with an impedance bandwidth of 10.53 GHz. The results are compared with 17 micron bulk copper patch antenna. The nanofilm antenna presents a wide bandwidth and higher return loss over bulk patch antenna. The antenna design, nanofilm thickness modeling, antenna simulation and results are discussed. The proposed antenna can be realized using nanotechnology systems like PVD, CVD, RF sputtering etc by depositing nano level thickness metals on FR4 substrate.
