In the given figure 2, simulated and measured S11 plots of an antenna designed are given. i. Simulated without defected ground structure (DGS), ii. simulated with DGS, iii. Measured with DGS.

State the impedance bandwidth of these three S11 plots and the points where resonances occur in each plot. 13. $11 (dB) -10 -20 -30 -40 24 26 28 Simulated without DGS Simulated with DGS -Measured with DGS 30 32 Frequency (GHz) Figure2: S11 vs. frequency plot of the antenna. 34 36 38 40
