一种异质基板集成的宽带液晶相控天线阵
By integrating a broadband liquid crystal phased array antenna with a heterogeneous substrate, the dielectric constant of the liquid crystal layer is controlled and non-contact energy coupling is used to solve the problems of limited bandwidth and poor integration of traditional phased array antennas. This enables multi-dimensional beam scanning and shaping, improving the performance and reliability of the antenna.

AI Technical Summary
Traditional phased array antennas have limited bandwidth, making it difficult to achieve multi-beam movement modes. They also have poor integration, large size, and high cost.
A broadband liquid crystal phased antenna array integrated with a heterogeneous substrate includes a radiating array layer, a liquid crystal phase shifter, and a feeding network structure. Through heterogeneous substrate integration, beam scanning is achieved by controlling the dielectric constant of the liquid crystal layer. Non-contact energy coupling and independent bias network are used to achieve multi-dimensional beam scanning and shaping.
It achieves broadband operation, improves antenna integration and reliability, reduces antenna thickness, supports complex beam scanning modes and shaping, and enhances signal transmission efficiency and stability.
