antinode

This term describes the peak of oscillation in a standing wave, representing the spatial location where the medium moves with the greatest intensity. It stands in direct opposition to the node, which is the point of zero displacement. The term is primarily used in physics and acoustics to describe the geometry of resonance.

In radio frequency and microwave engineering, the concept extends to electromagnetic fields. Here, it identifies the specific physical coordinates where signal strength is at its maximum, making it a critical consideration for the placement of antennas to ensure optimal energy capture or transmission.
