INTEGRATED ANTENNA DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240022007 titled 'INTEGRATED ANTENNA DEVICE
Simplified Explanation
The integrated antenna device described in the patent application consists of a curved-surface transmitting array and an array antenna. The curved-surface transmitting array has multiple focuses to ensure uniform radiation gains. The array antenna is positioned between the curved-surface transmitting array and the focuses. By controlling the active RF module of the array antenna, it emits a first-order beam and performs beam scanning. The curved-surface transmitting array focuses the first-order beam to generate a second-order beam with high gain. The active RF module's beamforming feed excitation weight generation enables beam scanning. The array antenna can be formed by feeder antennas and a DSP dynamic group that organizes the feeder antennas into subarrays. The subarrays can generate different first-order beams for multi-point communications, which can be scanned in an interleaved fashion.

Original Abstract Submitted
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.
