Types of Antennas Flashcards
1
Q
What is an isotropic antenna?
A
A theoretical antenna that radiates equally in all directions in the shape of a sphere (dBi).
2
Q
What are the main elements that determine antenna gain?
A
Directivity and efficiency
3
Q
Describe EIRP
A
Effective isotropic radiated power. How much potential power your antenna has compared to an isotropic radiator
4
Q
What is half-power beamwidth?
A
The angular separation between the half-power points on the radiation pattern
5
