Fig.7 Equivalent circuit model of the proposed antenna
When this configuration of the equivalent circuit is simulated, the simulated reflection coefficient (| S11|) due to the equivalent circuit of the proposed antenna is very much similar to the simulated reflection coefficient of the proposed antenna which is shown in figure 9. This close resemblance of the simulated reflection coefficient (|S11|) of equivalent circuit and the full wave simulated reflection coefficient (|S11|) Ansoft HFSS signifies the correctness of the lumped circuit description or the equivalent circuit analysis of the proposed antenna shown in figure 7.
