Far-Field Pattern

The far-field pattern describes how a radar, antenna, or radio wave source distributes its energy at a distance, typically far away from the source itself. It shows the directions where the signal is strongest or weakest, similar to how a flashlight beam spreads out. This pattern helps engineers understand and optimize how well the device transmits or receives signals over long distances. Essentially, it maps the "shape" of the signal's reach and strength in space, revealing the effectiveness and focus of the antenna's radiation in different directions.
