Benefits

  • Enables comparative analysis of multiple antennas under identical transmission scenarios
  • Simulates realistic power loss using free space path modeling
  • Helps engineers select the most efficient antenna for specific coverage areas
  • Supports trade-off analysis for transmission power, antenna size, and coverage
  • Reduces prototype iterations by providing signal behavior insights early in design

The Antenna model in VisualSim Architect is designed to evaluate and compare the performance of various unidirectional, OMNI, Phased-=Array, Radar and VSAT (Very Small Aperture Terminal) antennas from all commercial vendors. This model simulates a complete RF, 5G/6G and satellite communication setup, featuring a satellite station transmitter and multiple user terminals acting as receivers, a communication jammer with multiple antennas, and a radar tracking system. It helps engineers analyze transmitted vs. received signal power and optimize antenna selection and placement.
