Summary: | Telecommunication and wireless local area network (WLAN) technologies are increasing
rapidly within this few decades. The technology revolution occurred due to wireless
communication is more and more commonly used in everyday life for user and customers.
Due to that, multiple antennas system was been developed in order to cope the high
demand from users and customers. The multiple antennas known as multiple input
multiple output (MIMO) system can enhance the channel capacity and increased the output
performance of the system. Therefore, this system does not require an extra bandwidth or
increasing the transmit power. Based on that, the objective of this project was to predict
the MIMO performance at operating frequency was 2.4 GHz. The beamforming network
and microstrip array antenna was designed, fabricated and measured at desired operating
frequency. In this project, Microwave Office software was used to design the
beamforming network, while Computer Simulation Technology (CST) software was used
to design the microstrip array antenna. Both designed has been fabricated using etching
technique and the Advantest Network Analyzer was used to measure the performance of
the designs. The simulation and measurement data were been compared and discussed.
The fabricated bearnforming network and microstrip antenna were used to develop the
Radio Frequency (RF) MIMO test bed system. The system measurement was been
conducted in Microwave Laboratory at Faculty of Electronic and Computer Engineering,
UTeM with the operating frequency 2.4 GHz. The spatial diversity, polarization diversity
and beamforming network were been applied in measurement campaign to investigate the
performance of wireless MIMO channel. The data that obtain from the measurement will
be post-process using MATLAB software in order to calculate the MIMO channel
capacity. The analysis will be focused on the effect of the MIMO channel capacity due to
the proposed measurement setup configurations |
