Hi,
The patch antennas can be designed using the Antenna Toolbox and the results can be compared for the Microstrip Patch antenna and the E-Shape antenna.
Also, you may look into the following code that creates antennas and compares the results between the Microstrip Patch antenna and the E-Shape antenna. It may provide your further clarity:
ant1 = patchMicrostrip;
ant1 = design(ant1,2e9);
figure,show(ant1)
spar1 = sparameters(ant1,linspace(1.8e9,2.2e9,11));
figure,rfplot(spar1);
figure,pattern(ant1,2e9)
figure,vswr(ant1,linspace(1.8e9,2.2e9,11));
ant2 = patchMicrostripEnotch;
ant2 = design(ant2,2e9);
figure,show(ant2);
spar2 = sparameters(ant2,linspace(1.8e9,2.2e9,11));
figure,rfplot(spar2);
figure,pattern(ant2,2e9)
figure,vswr(ant2,linspace(1.8e9,2.2e9,11));
