Category - Far Field
These articles explain how to plot the far-field radiation patterns from an antenna or scattered by obstacles in various forms such as 2D charts, 3D radiation patterns, and polar diagrams. They also cover powers delivered, consumed, and radiated.
Articles
Explore 2D far-field patterns using AN-SOF. Visualize conical and vertical cuts, analyze metrics like power density, directivity, and gain. Decompose into polarization components and understand axial ratio. Plot in rectangular or polar charts for comprehensive analysis.
Visualize 3D far-field patterns in AN-SOF. Analyze power density, directivity, gain, and axial ratio. Decompose into polarization components. Rotate, zoom, and animate the 3D plot. Customize surface and mesh settings. Export far-field data to CSV.
Far-field frequency spectra are obtained when a simulation is performed by specifying a list of frequencies or a frequency sweep. For each frequency, the far-field is calculated at the several directions given by the zenith (Theta) and azimuth (Phi) angular ranges and...
