Optimal Antenna Positioning for Wireless Board-To-Board Communication Using a Butler Matrix Beamforming Network

For wireless board-to-board communication the problem of an optimal positioning of antenna arrays on two boards facing each other is described, where each antenna array uses the same kind of Butler matrix beamforming network. We discuss possible design criteria for the positioning problem. To obtain a position with both a high response and a low pathloss for as many as possible links we introduce a corresponding optimization problem and show how it can be solved.
