polar radiation pattern

[′pō·lər ‚rād·ē′ā·shən ‚pad·ərn]
(electromagnetism)
Diagram showing the relative strength of the radiation from an antenna in all directions in a given plane.
(engineering acoustics)
Diagram showing the strength of sound waves radiated from a loudspeaker in various directions in a given plane, or a similar response pattern for a microphone.

The beam steered polar radiation patterns (E plane) at the centre frequencies without considering SLL constraints are shown in Figures 10 and 11.
Figure 12 presents the impact of a 30-degrees twisting angle on measured ii-plane polar radiation patterns for patch 2, located close to the maximal mechanical strains zone (close to the twisting systems) for the conventional (red curves) and MTM (blue curves) antennas.
However, one prime characteristic that determines how any of them will interact with differing microphone techniques will be the polar radiation patterns of a pair of them (or of a larger group of speakers if a surround-sound installation is involved) and the way those patterns interact with room boundaries.
