The bandwidth can be calculated from the s11 graph. In the case of defining the antenna to be matched under -10db. a y marker could be placed by right click on the graph-->Add marker --> Add y-marker. then placing the y-marker on -10dB the bandwidth could be calculated from the X values (frequencies) as it is the difference between f2-f1=Bandwidth. f2 is the high frequency (2nd frequency) at which the S11 is intersecting the marker and f1 is the low frequency (1st frequency) at which the s11 and the marker are intersecting. By this you have the range of frequencies (Bandwidth) that the antenna is said to be matched under -10dB.
Sir....i need patch array antenna..any video's available????
Thanks for the video! this helped me a lot!!
Great video, thanks for sharing.
Thanks! Is there any way to extract bandwidth directly from the S11 graph?
