  • Abstract:
  • Wireless communication is the transfer of information between two or more points that do not use an electrical conductor as a medium for the transfer. Antenna array are inevitable component in any microwave communication system that demands large coverage. With the advancements in communication technology, modern transceivers are required to operate in multiple bands. MIMO (multiple input, multiple output) is an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver). The antennas at each end of the communications circuit are combined to minimize errors, optimize data speed and improve the capacity of radio transmissions by enabling data to travel over many signal paths at the same time. Multiple-input multiple-output MIMO technology has been attracting extensive attention in wireless communications, owing to its advanced characteristics of high channel capacity and spectrum efficiency. The replication of identical antenna elements improves the overall radiation performance for long distance communication However, for a size-constraint MIMO device with physical limitation for antennas installation, the service performance is always degraded by the interferences through mutual couplings among antenna elements. This mutual coupling performance degradation can be overcome by isolation enhancement. To achieve isolation enhancement, the use of electromagnetic bandgap (EBG) structures, defected grounded structures (DGS), meta-materials, split ring and complementary split ring resonators (SRR & CSRR) can be used. In this project, the design of noveldual-layer mushroom (NDLM) and back-to-back E-shaped stubs for mutual coupling reduction between microstrip patch antennas. The antenna is studied from the aspects of isolation, return loss, current and electric field distribution, radiation pattern, and diversity performance in a frequency range of 2.45 GHz of -53 dB,gain of 7dBi.
