| Formatted contents note | Modern wireless communication systems demand multi–band operation, higher data rate, channel<br/>capacity and better link reliability. Such requirements can be met by the usage of multiple input<br/>multiple output (MIMO) antenna system. The complexity of the MIMO antenna system has been<br/>reduced by the implementation of frequency reconfiguration approach. The frequency<br/>reconfiguration characteristics has been achieved by introducing radio frequency micro–electro–<br/>mechanical–system (RF MEMS) switches in the antenna system. The features of RF MEMS<br/>switch that distinguish it from other existed active switches include low power loss, wide<br/>impedance bandwidth, low insertion loss and high isolation.<br/>The thesis presents a novel design of two element MIMO frequency reconfigurable antenna<br/>system consisting of two semi–circular ring–shaped strip–lines with a rectangular slot on the top<br/>conducting layer and a U–shaped slot on the bottom side of the substrate. The dimensions of the<br/>proposed antenna system are 32 × 98 × 1 mm3. Frequency reconfigurable characteristics of the<br/>proposed MIMO antenna system has been achieved by using single pole four throw (SP4T) RF<br/>MEMS switch. To achieve the better performance from the proposed antenna system, the SP4T<br/>switch has been used in the U–shaped slot etched in the ground plane of the substrate. The<br/>frequency reconfigurability of antenna system has been switched at the frequencies of 600 MHz,<br/>1.8 GHz, 2.4 GHz, 3.5 GHz and 5.5 GHz bands. Isolation greater than 15 dB has been achieved at<br/>all the operating bands without addition of any decoupler structure. The measured peak gains of<br/>3.4 dB, 3.8 dB, 4.3 dB, and 4.4 dB have been achieved at 1.8 GHz, 2.45 GHz, 3.5 GHz, and 5.5<br/>GHz respectively. Average peak radiation efficiency of 59% has been observed at all operating<br/>bands of MIMO frequency reconfigurable antenna system. The calculated envelop correlation coefficient (ECC) less than 0.04, diversity gain (DG) greater than 9.8 dB and total active reflection<br/>coefficient (TARC) less than –10 dB have been observed at all operating bands during operation. |
