Antenna Design & Radiation Patterns

The art and science of designing antennas — from half-wave dipoles and microstrip patches to Yagi-Uda arrays, horn antennas, and phased array beam steering for wireless communication and radar systems.

Antenna design transforms guided electromagnetic energy into radiated waves and vice versa. Every wireless system — from Wi-Fi routers and cell towers to deep-space communication dishes and radar installations — depends on antennas shaped to direct energy precisely where it is needed. The radiation pattern, gain, bandwidth, and impedance of an antenna are all determined by its geometry and the wavelength of operation.

These simulations let you visualize dipole radiation patterns, design microstrip patch antennas, optimize Yagi-Uda arrays for maximum gain, calculate horn antenna beamwidths, and steer beams electronically with phased arrays — all with interactive controls and real-time animated field patterns.
