Employing a compact PCB antenna array to detect the EMI noises for transceivers performance-based test

This paper first proposes a cost-effect test-bench design concept in which an embedded antenna array composed of 4 multi-band, dual-polarized antennas is utilized to measure the environment electromagnetic noises. Instead of the un- user-friendly metal-shielding environment or expensive chamber room solutions, the proposed ATE can be used to clarify the root-cause and to improve the low yields issue when performing RF testing suspected by EMI interferences.
