Optimization of Antenna Pair for Diversity Gain

Abstract [en]

In the latest development in the field of telecommunications it has been observed that a lot is expected from the mobile systems. All kinds of communication standards such as Bluetooth, 3G, W-LAN etc. should be present in the same handset. This requires higher data transmission rates and low bit error probability. One of the major problems in achieving this is fading and multi path environment. The other problem is the growing trend of decreasing size of the electronic devices specially handsets. The handsets are getting smaller and thinner. Due to this the antennas in the device come very close to each other which causes high coupling between the antennas resulting in bad diversity gain. Antenna diversity is considered to be one of easier solution to overcome these problems. This thesis presents an implementation of receiver antenna diversity and suggests different optimised networks between the antenna ports for better diversity gain keeping in view the antenna efficiencies. The thesis involves the following steps: simulating the structures, suggesting different networks between the two antenna ports, optimisation and hardware implementation of the networks and finally measurements in reverberation chamber.
