Dear Dhiman,

welcome,

By convention the recommended bandwidth is the -3dB bandwidth. Which you termed it FWHM. So all you need to draw a horizontal line with a dB scale= dB at maximum of the major lobe - 3dB , This bandwidth is called the double sided -3DB bandwidth. You can determine it a suitable cursor.

Best wishes

Dhiman Kakati

Sir,

Should I ignore all the side-lobes and find out the FWHM from major lobe only?

Regards,

Dhiman
