Area of Science:

  • Electrical Engineering
  • Electromagnetics
  • Imaging Systems

Background:

  • Integrated packaged phased array receivers are crucial for passive millimeter-wave imaging systems.
  • Mutual coupling between receiver channels degrades imaging quality by introducing amplitude and phase errors.

Purpose of the Study:

  • To analyze the impact of channel mutual coupling on phased array receiver performance.
  • To propose design requirements and methods for mitigating mutual coupling in Ka band receiver front-ends.
  • To develop an accurate measurement technique for multi-channel integrated receivers.

Main Methods:

  • Analysis of channel mutual coupling effects on array patterns and amplitude/phase errors.
  • Modeling and design of passive circuits to reduce coupling and spatial radiation.
  • Development of a novel coupling measurement method for multi-channel integrated phased arrays.

Main Results:

  • Achieved 28-31 dB single channel gain and a 3.6 dB noise figure.
  • Reduced channel mutual coupling to below -47 dB.
  • Verified array pattern consistency and imaging performance in a 1024-channel system and human-body imaging experiment.

Conclusions:

  • The proposed methods effectively minimize channel mutual coupling in integrated packaged phased array receivers.
  • The developed receiver front-end demonstrates high performance suitable for passive millimeter-wave imaging.
  • The coupling analysis, design, and measurement techniques are broadly applicable to similar multi-channel integrated devices.
