Abstract: An arrayed RF system includes an expandable mother circuit carrier and sub-modules implemented with RF packaged radiation structures. The sub-modules are embedded onto the mother circuit carrier through plug-in interfaces to form a replaceable and expandable co-structural structure. The mother circuit carrier receives and up-converts an input intermediate-frequency signal, thereby generating first high-frequency signals. The sub-modules are horizontally embedded on the mother circuit carrier, arranged into a one-dimensional or two-dimensional array, and electrically connected to the mother circuit carrier. The RF packaged radiation structures respectively receive first high-frequency signals, thereby emitting first RF signals. The RF packaged radiation structures receive second RF signals, thereby generating second high-frequency signals. The mother circuit carrier down-converts the second high-frequency signals, thereby generating an output intermediate-frequency signal.

Abstract: An integrated antenna device comprises a curved-surface transmitting array and an array antenna. The curved-surface transmitting army has a plurality of focuses to homogenize its radiation gains. The array antenna is arranged between the curved-surface transmitting array and the plurality of focuses. According to the control of an active RF module of the array antenna, the array antenna emits the first-order beam and performs beam scanning. The curved-surface transmitting array is used to focus the first-order beam to produce a second-order beam with high gain. The generation of the beamforming feed excitation weight of the active RF module makes the integrated antenna device have a beam scanning mechanism. The array antenna can be formed by feeder antennas A DSP dynamic groups the feeder antennas to form subarrays, the subarrays can generate different first-order beams for multi-point communications. The first-order beams can be scanned in an interleaved fashion.
