radiation diagram
Noun: A graphical representation, typically in polar or Cartesian coordinates, showing how the intensity of radiation (e.g., radio waves, light) from a source, such as an antenna or a light, varies with direction or angle. It visually maps the strength of the emitted signal in different directions around the source.
This term is a technical noun used primarily in physics, engineering, and telecommunications. It describes a specific type of scientific diagram. * The engineer analyzed the radiation diagram to optimize the antenna's broadcast coverage. * A symmetrical radiation diagram indicates the antenna emits signals equally in all horizontal directions. * The textbook included a radiation diagram showing the satellite dish's signal pattern.
- Polar vs. Cartesian Coordinates: A radiation diagram can be plotted on a polar graph (showing angle and distance from the center) to easily visualize directionality, or on a Cartesian graph (with X and Y axes) to plot gain against angle.
- The polar radiation diagram clearly showed the main lobe and the side lobes of the transmission pattern.
- Synonyms in Technical Contexts: In many professional contexts, "radiation pattern" or simply "pattern" are more common synonyms for radiation diagram.
- Radiation Pattern (n): The most common direct synonym for radiation diagram.
- Antenna Pattern (n): A specific term used when the radiation source is an antenna.
- Lobe (n): A part of the radiation diagram where the signal is strong. Terms like "main lobe" (strongest signal direction) and "side lobe" (weaker, off-axis signals) are used to describe its features.
- Isotropic Radiator (n): A theoretical point source that would produce a perfectly spherical radiation diagram.

- Plot a radiation diagram: To create or generate the graphical representation.
- The software is used to plot the radiation diagram of the new antenna design.
- Main lobe of the radiation diagram: Refers to the primary direction of strongest radiation.
- The antenna should be aligned so the main lobe of its radiation diagram points toward the receiver.
- graphical representation (in polar or Cartesian coordinates) of the spatial distribution of radiation from an antenna as a function of angle
