Stable Phaseless Spherical Antenna Measurements via Mixed-Norm Regularization

The phaseless characterization of radiated field of antennas is a promising alternative to ease the measurements and to reduce the cost of measurement setups. However, phaseless procedures are dragged down by significant constraints such as the number of required field samples and convergence problems. This article improves on a previous work by proposing a simple yet efficient spherical, phaseless, measurement procedure based on an adaptive mixed-norm regularization.
