Abstract:
The 5G communication technology is seen as a breakthrough in wireless communications, as current smart phones demand a very wide band width. This rapid transformation motivates researchers in communication technologies, whether in software or hardware. Additionally, antenna design is regarded as a fundamental topic that requires ongoing development to serve 5th Generation wire-less communication networks. The major objective of the thesis is to advance a dual band multiple input multiple output MIMO antenna that can serve 3G and 5G mobile communication systems while including all the essential features of modern wireless communication systems. It is pertinent to note that this thesis emphasis on 8×8 MIMO antenna model with explanation about the chronological growth, basic factors and the sorts of antennas which are applied in 5G mobile phones. Mobile phones antenna design section consists of two antennas namely Upturned U-Shaped and Upturned F-Shaped. Inverted U-shaped design operates at 3.5 GHz while the Inverted F-shaped design generates resonance at 5.5 GHz frequency. The return loss of 3.5 GHz band and 5.5 GHz bands are -29.5 dB and -41 dB separately. The impedance bandwidth at both bands is 1700 MHz and 700 MHz respectively. The efficiency of the antennas are 95 percent. The simulations of 8×8 MIMO Antenna are performed in CST. The simulation meets with measured results showing the validation of design.
