Radiation Pattern Lobes
A radiation pattern lobe is a section of the radiation pattern surrounded by regions of relatively weak radiation intensity.
- Major lobe / main beam
- The lobe in the radiation pattern containing the direction of maximum radiation.
- Side lobe
- The lobe in any direction other than the intended lobe and usually represent radiation in undesired directions.
- Back lobe
- The lobe in the radiation pattern that is in the opposite direction of the major lobe.
- Side lobe attenuation
- Back lobe attenuation
- 3dB angle of main lobe
- 3dB angle of side lobe
