    Research Work
    1. Ph.D Thesis Work (2010 onwards): Millimeter Wave Laboratory,
    Department of Electronics and Communication Engineering, IIT Roorkee
    Title: Investigation on Specific Microstrip Filters with Defected Ground
    Structure
    Supervisors: Dr.M.V.Kartikeyan
    Brief Description: Filter is the very essential component of communication system
    with compact size to the conventional counterpart. In the new era of Wireless
    communication, the filter should be compact, low profile with sharp transitions. So
    the design parameters should be chosen in such a manner that the overall
    performance such as VSWR, impedance bandwidth, return loss, insertion loss,
    suppressed harmonics etc. given by the filter should be better. For this
    purpose, I am working on the filter size reduction techniques, multiband design
    techniques, bandwidth enhancement techniques, etc. The artificial neural network
    (ANN) is being used for the analysis of microstrip filters, Wave iterative method is
    being used for analysis of Microstrip. In addition the one dimensional photonic
    band gap structures called defected ground structure (DGS) is also used and
    incorporated in the microstrip filters for the further improvement of filters
    properties such as size reduction, Bandwidth enhancement, sharp transitions,
    higher order mode suppression.
    Design study of some specific microstrip filters like low pass, high pass,
    band-pass, band-stop, CSRR filters, and tunable filters along with the defected
    ground structure has been carried out as the research work. As the DGS has also
    been used in the design of antennas; Multiband antennas with different
    topologies and not much work has been reported by the researchers in this
    regard. Therefore it becomes necessary to see the effect of the DGS in
    specific filters and to study their performances. The simulation process is
    done by the CST microwave studio, ADS, and Ansoft HFSS. Measurement
    and fabrication is also being carried out. Further the study on numerical
    techniques such as FDTD, MOM, and FEM etc have also been carried out.
    In addition some mini projects are completed:
    1. Design of a filter calculator using MATLAB.
    2. Design of Microstrip Bandpass filter at for WiMax applications.
    3. Design of Microstrip seven pole low pass filter for WLAN applications.
    4. Design of Equal-split Wilkinson power divider.
    5. Design of a 50 ohm line branch line coupler.
    6. Design of a 20dB single-section backward coupling microstrip line.
    2. M.Tech Thesis Work (2008-10): Microwave Laboratory, Department of Electronics
    and Communication Engineering, Graphic Era University, Dehradun
    Title: Design of microstrip seven pole low pass filter with defected ground
    structure
    Supervisor: Dr.R.Gowri
    Brief Description: A Problem related on the design of a seven pole low
    pass filter for sharp transitions with size reduction to conventional type
    filter with hexagonal metal shaped DGS and comparison of the various
    topologies of DGS for wireless applications such as WLAN, WiMAX and Wi-
    Fi. 2. Design various type of DGS shape using only the
    50 ohm line and the DGS slot is etched in the ground plane of the
    Microstrip line and study of their characteristics the results of this proposed
    hexa-metal shaped DGS shows the very sharp transition comparison to the
    convention seven pole Microstrip filter with large bandwidth and high power
    handling capacity and all the simulations are carried out using Ansoft HFSS
    V10. The important factor to use the DGS structure is to reduce the size of
    filter up-to 70 percent.
