64-Element Helix Antenna Array
The antenna array includes 64 helix elements, and each helix element has an isolation PEC skirt to reduce the coupling and dielectric support. Ignoring the thickness of PEC skirt and helix structure, GEMS can simulate it using less than 4 GB of memory. GEMS can simulate the arbitrary feed patterns with different phase and amplitude distributions, and calculate the far field pattern, s-parameter matrix, total reflection coefficient, and co-polarization and cross polarization.
