  • DESIGN AND ANALYSIS OF MIMO PATCH ANTENNA FOR 5G WIRELESS COMMUNICATION SYSTEMS
    Pallavi H. V, A P Jagadeesh Chandra, Paramesha
    International Journal of Computer Networks and Communications, 2022
    In this work, the circular array microstrip patch antenna (MPA) design is proposed for the 5G wireless communication and the millimeter- wave frequency being utilized for this communication system to enhance the coverage area. Here, the Multi Input Multi Output feeding technique is utilized to improve the performance of the proposed design at a resonant frequency of 35 GHz with RT-Duroid 5880 material as substrate. It has 2.2 dielectric constant value and the thickness is 0.5mm.The simulation analysis has obtained the gain as 8.8dB and return loss as -41.9dB. Also, two MPA designs such as single element MPA and 2x2 rectangular array MPA are designed to validate the proposed antenna design. A comparative analysis has proved that the circular array MPA is preferable for the 5G wireless communication system compared to the other two designs such as single element MPA and 2x2 rectangular array MPA.
  • Design and Performance Analysis of MIMO Patch Antenna using Superstrate for Minimization of Mutual Coupling
    Pallavi H. V., A. P. Jagadeesh Chandra, Paramesha Paramesha
    Wseas Transactions on Circuits and Systems, 2022
    For 5G communications, An different types Antennas are plays major role to minimize mutual couplings and here MIMO is important technology which uses patch antenna’s. Where the existing design focuses only on frequency reconfiguration, but it does not take advantage of the entire frequency and power spectrum. Therefore, the honeycomb-shaped Metamaterial cells used in the suggested antenna design serve as a superstrate for micro-strip patch antennas with a extensive range of actual negative permittivity and permeability, as well as a refractive index feature. Also, to reduce mutual coupling in current printed and other antennas. A metamaterial superstrate-based micro-strip antenna with RF MEMS Varactor diode switching is proposed in this paper. Based on a micro-strip antenna, metamaterials in the shape of circular and hexagonal arrays are employed as the superstrate. Also, the superstrate layers serve as a random, providing strength to the entire structure while also improving other antenna metrics such as gain and bandwidth. The design outputs for several metamaterial superstrates in terms of reflection coefficient (S11), gain, and bandwidth are compared by adding varactor diode switches to the metamaterial superstrate, which also allows for frequency reconfiguration. As a result, the suggested antenna was designed to reduce mutual coupling and improve system performance in 5G technology, specifically in mm-wave applications. The obtained results for metamaterial superstrate designs demonstrate high bandwidth and gain behavior.

  • Line and word segmentation of Kannada handwritten text documents using projection profile technique

    Historic handwritten documents are valuable traditional legacy, as they deliver insights into both tangible and intangible cultural features since the ancient time. Handwritten historical documents stance real experiments for involuntary processing, such as image binarization and segmentation. Segmentation of handwritten pages interested in text lines and words is problematic as the script is not unique and the lettering differs a lot contingent on the writer and yet, it is a significant phase for the recognition of content. In this paper we have presented a segmentation system based on Projection Profile method for general handwritten text and historical handwritten text. The system includes procedures for preprocessing, the preprocessing of text image consists of noise removal, binarization, skew detection and correction, following these preprocessing steps, the text image is split into individual text-lines then these text-lines to individual words. The proposed algorithm provides 90% successful segmentation achieved in line segmentation and but word segmentation level needs more effort as it is complicated for Kannada script. The accuracy is reduced due to lack of space between the text-lines and overlapping of subscripts.

    A. P. Jagadeesh Chandra, C. R. Venugopal
    IEEE Transactions on Instrumentation and Measurement, 2012
    Laboratory experiments are integral part of science and engineering education. Automation is changing the nature of these laboratories, and the focus of the system designer is on the availability of various interfacing tools to access the laboratory hardware remotely with the integration of computer-supported learning environment. This paper presents the novel design techniques to access experiments on electrical machines remotely through the Web using virtual instrumentation (VI) tools. The general Web-interface architecture is presented to facilitate control and measurement of experimentation parameters online with complete isolation from the electrical line voltage. LabVIEW-supported VI tools are used to create the Web-based automation and control of the experiment hardware. The custom-built electrical hardware is designed to interface the Web server with the experimental resources and to support user-friendly interface to access the data online. The safety issues while operating the electrical machines online are addressed through the control logic designed by the graphical code. The designed system exploits the data acquisition and the LabVIEW features to extend the dc motor and generator experimentation online along with the acquired data that are presented in virtual meters as well as in graphical plots.

    Attaining excellence in technical education is a worthy challenge to any life goal. Distance learning opportunities make these goals easier to reach with added quality. Distance learning in engineering education is possible only through successful implementations of remote laboratories in a learning-by-doing environment. This paper presents one such technology to carry out laboratory experiments from remote locations. The technology is demonstrated by handling the web interface, which supports the remote experimentation on communication circuits, power system and an embedded board. The implemented system environment facilitates users to perform the experiment remotely and efficiently using only a commonly available, user-friendly web browser. It describes the ongoing research in this area exploiting current telematics techniques, which supports remote experimentation with real hardware via the Internet.
