The DGS is one of the key important structures to gain multiband characteristics from MSP antennas. In this work, F-shaped monopole with DGS are placed to enhance the performance of the antenna bandwidth including dual band, triple band and multiband characteristics and to reduce the harmonics.
The modelled DGS monopole antenna is working at multiband and showing size reduction to get LC resonant properties in the medical band.
By placing DGS in the proposed antenna base, additional operating frequencies are gained due to the unequal change in the current distribution path of the antenna.
The modelled antenna is fabricated on FR 4 substrate material and measured results are noted from Anritsu combinational analyzer (vector network analyzer + spectrum analyzer).
The simulation results from HFSS are in good matching with measured results from fabricated antenna model.
