Conference paper

Array antenna diagnostics with the 3D reconstruction algorithm

In Proceedings of the 34th Annual Symposium of the Antenna Measurement Techniques Association — 2012, pp. 117-121

The 3D reconstruction algorithm is applied to a slotted waveguide array measured at the DTU-ESA Spherical Near-Field Antenna Test Facility. One slot of the array is covered by conductive tape and an error is present in the array excitation. Results show the accuracy obtainable by the 3D reconstruction algorithm.

Considerations on the measurement sampling, the obtainable spatial resolution, and the possibility of taking full advantage of the reconstruction geometry are provided.
