Abstract
Analysis of polarization optimization of dualpolarized compact arrays for direction finding, which include Decoupling and Matching Networks (DMNs) comprised of distributed elements, is performed in this paper. The CRLB for twodimensional Direction of Arrival (DoA) estimation is used as a figure of merit for the performance of five elements dualpolarized circular LQuad arrays, assuming different interelement spacings and the correspondent DMNs, designed with the aim of decoupling and matching the compact arrays, with interelement spacing smaller than half of the freespace wavelength. Owing to the dualpolarimetric characteristic of the antenna array investigated, it is possible to optimize the DMN to decouple and match the array elements for the direction finding of impinging electromagnetic wavefronts.
