A Compressed Sensing-Based Element Failure Diagnosis Method for Phased Array Antenna During Beam Steering

IEEE Antennas and Wireless Propagation Letters, 2019
A novel diagnosis method for phased array antenna element failure using near-field measurements based on compressed sensing is proposed. In consideration of the beam steering property of phased arrays, sampling of the radiated field is performed with ...

Phased Array Antennas

1971 2nd European Microwave Conference, 1971
The theory of array antenna design has matured such that the tools are now available to design elements with predictable performance and to verify this performance with high confidence. The antenna feed is of equal importance to the antenna element.

Phased array antennas

1993
This chapter is a comprehensive treatment of phased arrays, including (1) array theory, analysis and synthesis techniques; (2) the detailed treatment of array elements and mutual coupling effects; and (3) active arrays - architectures, transmitter-receiver (T/R) modules, feed and control, design criteria and low-sidelobe techniques.
