摘要：

This paper aims to develop an intelligent radiocommunication prototype using multiple-antenna phased array whose bearing can be controlled electronically. Such a system has proved its efficiency in terms of gain and SNR improvement. The architecture presented in this article runs at 2.4 GHz with a bandwidth channel of 11 MHz which is well suited for WIFI 802.11b applications. This original system uses quadrature modulators as active phase-shifters, and noise sensitivity is studied and simulated to prove the interest of this architecture. A circuit is under tests and first elementary active parts RF measurements are given.
