Table 1.
Efficiency due to illumination (assuming no blockage and a primary reflector without surface errors) derived from QO-GBFM and PO methods at Q and W bands.
| Method | Q band (43 GHz) | W band (87 GHz) |
|---|---|---|
| QO-GBFM | 0.81 | 0.81 |
| PO | 0.80 | 0.82 |
Notes. The QO-GBFM method uses the theoretically designed feed patterns and an analytical method. The PO method uses the real feed patterns and a numerical procedure.
