Near-field Pattern

A near-field pattern describes how electromagnetic energy is distributed close to an antenna or source before it transitions to the far-field zone. Think of it as a detailed map of how the signal behaves right near the antenna, where the field is complex and varies significantly. This pattern shows the strengths and directions of the electromagnetic waves within a short distance, providing critical information for designing and optimizing antennas. Beyond this near-field zone, the waves spread out more uniformly, forming the far-field pattern used to analyze signal reach and coverage.
