Compact Quasi Self Complimentary 2/4-Port MIMO Antenna For Wireless Applications

Abstract

Over the most recent couple of decades, the developing interest for high information rates in remote correspondence has constrained antenna designers to search for an innovation that can give high information rates. Multiple input multiple output (MIMO) is technology, where multiple antenna are used at both transmitting and receiving terminals. In such systems, multiple independent channels are created, which increases the data rate significantly, without any requirement of bandwidth or transmitting power. In this thesis, designs are presented which relies on self-complementary structures. The feeding of designs are done by microstrip line. The antennas consists of two radiators present on the substrate. As the geometry is compact quasi self-complimentary, therefore ground and patch (radiators) are present on the same height. The two radiators are fed by using two quasi self-complimentary feedlines. In this, the fully recommended HFSS procedure is followed. Substrate of particular dimensions are taken and patch is also designed on the substrate. The dimensions of various elements of substrate are varied on the basis of simulations. The designs are analysed and its parametric optimizations are done on HFSS software. The final results are fabricated. The goal of this work is to improve the performance of Multiple input multiple output system (MIMO) antenna system in terms of radiation efficiency and isolation between the antenna elements
