Terence Chan's video: Pocket Antenna Array Analyzer with 3D far-field radiation pattern

Hi, below is the original description of the app: Listed as one of "10 iPhone-Apps für Ingenieure und Elektronik-Entwickler" by the German electronics magazine Elektronikpraxis Antenna array simulation tool providing 2D, 3D far-field radiation pattern, directivity, and normalized electric field intensity at a specific location with beam (electromagnetic wave) steering phased array capabilities 3D FAR-FIELD RADIATION PATTERN: Selectable scale - Linear, dB Array source view - approximate layout Antenna array directivity Colored axis - x(red) y(green) z(blue) Array factor intensity at a specific location Color coded Legend Angular grid ARRAY SETTINGS: Properties for all major axis Spacing Number of elements User-defined arithmetic phase for beam steering phased array Binomial - No side lobe Tapered - Stronger side lobe Dolph-Chebyshev - Controlled side lobe Customized - Edit magnitude & phase and create your own array Conventional, loop, ring and hexagonal shape array design Spacing Offset 2D FAR-FIELD RADIATION PATTERN: Three primary planes XY - theta(90°) phi(0°~360°) YZ - theta(0°~180°) phi(0°) ZX - theta(0°~180°) phi(90°) Selectable scale (dB, Linear) Cartesian and polar coordinate ANTENNA TYPES: Isotropic (Ideal) Dipole (short / conventional) Antenna Pyramidal Horn Antenna Microstrip Patch Antenna ADDITIONAL FEATURES: Higher resolution mode Rotating animation Zoom in/out by pinching Rotate by swiping Reset the scene by triple tapping Easy frequency / system unit change Email simulation report ipa at https://tinyurl.com/array-analyzer-ios
