Development and Analysis of Wideband Microstrip Patch Antenna for MIMO System

Abstract

The higher data throughput and channel capacity requirements of wireless newlinecommunication can be satisfied by increasing the signal bandwidth or numerous antenna. newlineTraditional wireless communication Single Input Single Output (SISO) system used to newlinetransmit and receive data but channel capacity of this system cannot capture the large data newlinevolume. Multiple Input Multiple Output (MIMO) is one of the emerging wireless radio newlinecommunications technology and afford higher data rate, greater quality of service and newlinespectral efficiency. MIMO technology has important consideration in next generation newlineunguided communications standards because it offers upgrades in data rate and wide newlinecoverage without demanding extra power, greater spectral efficiency and decreased fading. In newlinetoday s environment to achieve wider bandwidth and greater isolation characteristics, antenna newlinerole is very significant. Researchers have been urged to deploy wideband antenna to enhance newlinethe features of MIMO system by improving the construction of patch antenna for MIMO newlinesystem. newlineDevelopment of wideband microstrip patch antenna for MIMO systems is the fastest newlinefield of technology which has conquered the consideration of forthcoming life in the newlineunguided Communications due to their spectral efficiency. In unguided communications the newlinespectral efficiency and interference is most pressing problems in the next decade. MIMO newlinesystems provides guarantee to reach higher data throughout and there with greater spectral newlineefficiencies. newlineThe proposed research work provides extensive studies on design, development and newlineanalysis of different wideband microstrip patch antenna and their 2x1 MIMO newlineimplementation. The proposed antenna indicates the good operating frequency range and newlineresonances with an improved return loss, VSWR and bandwidth for wireless applications. newlineThe main aspiration was to develop a more a compact sized and wideband microstrip patch newlineantenna without downgrading its radiation characteristics like bandwidth, gain and efficiency. newlineMainly these antennas can cover ultra-wideband frequency range with good isolation newlinecharacteristics. The mutual coupling in MIMO system is the leading issue that downgrades newlinethe system fulfilment, which can be analysed by varying the distance between two antennas newlineand by using different configuration like orthogonal, side by side and front to front. Greater newlineeffort has been made in MIMO system to lower the mutual coupling. newlineviii newlineWideband patch antennas have constitute universal application. In next generation newlinecommunication system has its own merits such as compatibility, ease of integration low-cost newlinefabrication, light in weight, small in size, planar configuration, and greater motility, newlineapplicable for array with the comfort of fabrication and can be easily mounted on to any newlinedevice. A good design of antenna can step down the system requirement which increase the newlinetotal performance. It is very important for fruitful implementation of every unguided newlinecommunication system. newlineDesigned and analyzed both hexagonal spanner shaped line feed and compact newlinecoplanar square spanner shaped signal strip microstrip patch antenna along with their 2x1 newlineMIMO implementation. The designed antenna systems achieves ultra-wideband band newlinefrequency range, VSWR is lower than 2, ECC lower than 0.05, and mutual coupling is lower newlinethan -20dB. The designed antenna have good mutual coupling and envelope correlation newlinecoefficient are attained. newline
