SMD Coincident Antenna Array for 2D Field Acquisition and Reconstruction

Field acquisition and reconstruction by means of (near-)coincident arrays is quite consolidated in acoustics. Techniques such as Mid-Side, XY and Ambisonics, supported by algorithms for signal processing, paved the way to 2-dimensional and 3-dimensional sound recording and field synthesis, by placing microphones very close to each other in a single spot. On the other hand, the use of antenna coincident arrays for electromagnetic field acquisition is quite rare. This article proposes a preliminary study on the feasibility of coincident antenna arrays by means of surface mounted miniature chip antennas and the application of a 2-dimensional field acquisition technique such as Mid-Side to electromagnetism.
