In this section, the planar monopole antennas are
designed and the results of the input impedance and
radiation characteristics are presented below. It is essential
to accomplish a parametric study of geometry parameters
which affect the performance of the proposed antenna to
obtain a better insight of antennas behavior for design
purposes. The simulated results are obtained using the
ANSYS HFSS v.13 (High Frequency Structure Simulator)
3-D EM simulator.
