Question:
What is the radiation pattern of a point source antenna in free space?
What is the radiation pattern of a point source antenna in free space?
Show Hint
An isotropic antenna radiates uniformly in all directions, making it ideal for understanding antenna radiation patterns.
Updated On: May 5, 2025
- Isotropic
- Omnidirectional
- Bidirectional
- Directional
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
An isotropic antenna radiates equally in all directions, resulting in a uniform radiation pattern. This is a theoretical antenna used as a reference to compare the radiation patterns of real antennas.
