Abstract

Multiple Input Multiple Output (MIMO) technology is a promising approach to fulfil the demand of current wireless systems that requires higher data rate and larger capacity in a compact size. The main challenge in designing a MIMO antenna in a close packed space is to achieve high isolation between the antenna elements. This research study concentrates on the design and analysis of several small sized two - elements MIMO antennas that have a working frequency for the following applications, such as Bluetooth (2.4 GHz), LTE2300 (2.3 – 2.4 GHz), LTE2600 (2.5- 2.69 GHz), Wi-Fi (2.4 – 2.485 GHz), WLAN (2.4/5.2/5.8 GHz) and WiMAX (2.5/3.5/5.5 GHz). The proposed design were analysed with a different set of parameters. The aforementioned antennas are design by means of different methods that includes neutralization line technique, stub and defected ground plane to suppress the mutual coupling. The MIMO parameters such as mutual coupling, envelope correlation coefficient, total active reflection coefficient (TARC), capacity loss and channel capacity were investigated and analysed. All the proposed MIMO antenna design achieved satisfactory results with a reflection coefficient less than -10 dB, mutual coupling less than -13 dB and envelope correlation coefficient less than 0.5. Therefore, it could be concluded that all the proposed MIMO antenna designs demonstrated a considerable good performance and met the required prerequisite of a MIMO antenna.
