Abstract

Modern radio communication systems have to provide higher and higher data rates. Multiple antenna technologies (MATs) have gained much attention in the last few years because of the huge gain. MATs can enhance the communication reliability and the channel capacity levels. Furthermore, multiple antenna systems can have a big contribution to reduce the interference both in the uplink and the downlink. The idea behind multiple antenna diversity is to supply the receiver by multiple versions of the same signal transmitted via independent channels. In modern communication transceiver system, primary aims are to direct high power RF signal from transmitter to antenna while preventing leakage of that large signal into more sensitive front-end of receiver. So, a Single-Pole Double-Throw (SPDT) Transmitter/Receiver (T/R) Switch plays an important role. In this paper, study and design of smart distributed subarray MIMO (DS-MIMO) microstrip antenna system with controller unit has been introduced and investigated. All the entire proposed antenna system has been evaluated using a commercial software. The final proposed design has been fabricated and the radiation characteristics have been illustrated using network analyzer to meet the requirements for receiving diversity applications.
