摘要

Performance evaluation of a mobile WiMAX beam forming network (BFN) and design algorithm of using the RF digital Step attenuator (DSA) for implementing the BFN are described. The architecture of the BFN controller and the steering operation modes of the BFN are also introduced. Optimization of the antenna element spacing in considering of the mutual coupling against the grating lobe suppression is analyzed. The simulated performance evaluation in measuring a tested Butler matrix array antenna by BFN is evaluated. Relevant equations of the phase and amplitude error parameters used in the Monte-Carlo simulation are derived.
