Transceiver activo de bajo coste a frecuencia WLAN

In this paper, A new low-cost active antenna for WLAN sensor applications is presented. The proposed system operates as a transceiver whereby the received coded data signal from the broadside direction is retransmitted over a wide area in other directions. This is performed so that a null response at the main pointing angle is maintained. It is formed by a three elements series array connected to high performance FET-based down-and up-converters. The performance of the proposed architecture is verified using experimental results.
