This spiral antenna was optimized with EM simulation. Visualization of the log-scaled norm of the electrical field on the slotted surface and far-field radiation pattern of a spiral slot antenna. Wireless communication, sensing, positioning, and tracking. All of these technologies can take advantage of the spiral slot antenna's consistent radiation pattern and impedance over a large bandwidth. To optimize spiral slot antenna designs for particular applications, engineers can turn to EM analysis software that calculates S-parameters and far-field patterns. The COMSOL Multiphysics® software is used for simulating designs, devices, and processes in all fields of engineering, manufacturing, and scientific research. See how you can apply it to designing spiral slot antennas. comsol.blog/spiral-antennas Free Info at http://info.hotims.com/70471-636http://info.hotims.com/70471-636
