6Compact MIMO Antenna Systems
6.1 Introduction
MIMO technology uses multiple antennas at the transmitter and receiver to increase the channel throughput and achieve high data rate wireless communications by taking advantage of the space diversity. According to the Shannon–Hartley theorem, the maximum data rate where information can be transmitted over a communications channel is
(6.1)
where 
is the channel capacity in bits per second, 
is the bandwidth of the channel in hertz, and 
is the SNR. Considering a MIMO system with fixed linear 
matrix channel (
transmit and 
receive antennas) with additive white Gaussian noise, the MIMO capacity can be expressed as [1]
(6.2)
where is the average SNR and ...
