antenna radiation pattern
The antenna radiation pattern shows how an antenna radiates electromagnetic waves in space. It depicts the distribution of radiation intensity as a function of direction, indicating the antenna's performance in different directions.
Antenna Radiation Pattern
The antenna radiation pattern is a crucial characteristic of an antenna. It visually represents how an antenna emits electromagnetic waves across space.
Explanation
It shows the variation of radiation intensity with respect to direction. By analyzing the pattern, one can understand where the antenna radiates most effectively and where it has nulls or reduced radiation.
Structure
Typically, it is presented in a polar or spherical coordinate system. The pattern can be omnidirectional (uniform in all directions like a dipole in free space) or directional (stronger in specific directions, as in a dish antenna). Engineers use it to design antennas for specific applications, ensuring optimal radiation in the desired directions.
