ACTIVE ARRAY ANTENNA DEVICE |
摘要 |
In one embodiment, an active array antenna device includes: M (M≧2) bandpass filters to filter signals received by M antenna elements; M low noise amplifiers to amplify the filtered received signals; M distributors to distribute respective of the M amplified signals into N (N≧2) distributed signals; M sets of N phase shifters provided for respective of the M distributors to shift phases of the N distributed signals; M sets of N attenuators to attenuate N phase-shift signals; N beam synthesis circuits provided for N sets of the M attenuators to synthesize a beam by summing attenuator outputs from the M attenuators corresponding to the M distributors; a heat insulating container accommodating the low noise amplifiers and the receiving filters and formed of a superconductor material; and a cooler to cool the receiving filters and the low noise amplifiers to make the receiving filters in a superconducting state.
