Description

technical field [0001] The invention relates to the field of antennas, in particular to an electrically controlled phased array antenna and a module and system including the antenna. Background technique [0002] There are a variety of phased array antennas based on variable permittivity dielectrics. Chinese Patent Publication No. CN101283480A discloses a phased array antenna based on a nematic liquid crystal phase shifter, in which the liquid crystal is placed between the upper and lower plates of the microstrip line, and the liquid crystal molecules are deflected by applying a DC electric field and the dielectric constant is achieved. Control, thereby realizing the change of the transmission phase delay of the microstrip line on it. The device needs to hermetically seal the liquid crystal, which increases the complexity of the process and reduces the mechanical reliability; while the phase shift per unit length of the reflective microstrip line phase shifter used is low, ...

AI Technical Summary

Problems solved by technology

However, considering that the ferroelectric phase shifter has deviated from the optimal operating temperature, resulting in a narrowed phase shift range or increased insertion loss, this method still cannot completely overcome the performance degradation and increases the computational complexity.

[0003] In summary, the phased array antennas based on variable permittivity dielectrics in the prior art have the following disadvantages: high cost, complicated process for making circuit boards, large volume and weight, and no temperature compensation to stabilize the phase shifter
