10 Questions
What does the power pattern in dB represent?
The magnitude of the electric or magnetic field
How is a major lobe defined in a radiation pattern?
As the lobe containing the direction of maximum radiation
What type of lobe is a back lobe?
A lobe that is opposite in direction to the major lobe
How is a minor lobe defined in relation to a radiation pattern?
A lobe that is not a major lobe
What characterizes a side lobe in a radiation pattern?
It is present in any direction other than the intended lobe
In split-beam antennas, can there be more than one major lobe?
Yes, there can be multiple major lobes
Which type of radiation lobe occupies the hemisphere opposite to that of the major lobe?
Back lobe
What makes a radiation pattern lobed?
The strength of radiation at different angles
How are lobes classified in a radiation pattern?
As major, minor, side, and back lobes
What separates a major lobe from other lobes in a radiation pattern?
The direction of maximum radiation it contains
This quiz covers the radiation pattern of antennas, including the three electric-field components (πΈπ , πΈπ , πΈβ ) and their behavior in the far field. Learn about how different antennas may have varying numbers of electric field components based on their geometry and observation distance.
