GPS Antenna
The GPS antenna includes 4 pairs of antennas, antenna radome and antenna base. Due to the fine mechanic structure in the base, the project pre-processing will be very time consuming for a regular EM solver. However, using the domain decomposition technique, GEMS can complete the pre-processing and simulation in just 11 minutes. The output parameters are far field patterns, s-parameter matrix and total active reflection coefficient.
