  • An 8-Shaped Self-affine Fractal MIMO Antenna for UWB Applications
    Applications of Artificial Intelligence Techniques in Engineering, 2019
    Co-Authors: Rohit Gurjar, Dharmendra Kumar Upadhyay, Binod Kumar Kanaujia, Karishma Sharma
    Abstract:

    A compact 8-shaped self-affine fractal multiple-input-multiple-output (MIMO) antenna for ultra-wideband (UWB) communications presented. In order to achieve miniaturization and wideband phenomena, self-affine fractal geometry is used in the antenna design. The 8-shaped self-affine fractal geometry has been designed through iterated Function System (IFS) up to the second iteration. The antenna consists of two 8-shaped self-affine fractal monopole antenna elements, a ground stub and vertical slots cut on the ground stub to enhance isolation and increase impedance bandwidth. The proposed antenna has compact dimensions of 26 × 40 mm2 and impedance bandwidth (S11 < −10 dB) from 3 to 10.6 GHz with an isolation better than 19 dB over entire UWB. The various diversity performance parameters are also determined such as ECC, MEG, TARC and CCL, and all such parameters are within their allowable limits. These all results show that the proposed 8-shaped self-affine fractal MIMO antenna suitable for UWB applications.

  • Compact four-element 8-shaped self-affine fractal UWB MIMO antenna
    2018 3rd International Conference on Microwave and Photonics (ICMAP), 2018
    Co-Authors: Rohit Gurjar, Dharmendra Kumar Upadhyay, Binod Kumar Kanaujia
    Abstract:

    A compact four-element 8-shaped self-affine fractal UWB MIMO antenna is presented. The self-affine fractal structure provides miniaturization and wideband characteristics to the antenna. The 8-shaped self-affine fractal geometry is designed up to the second iteration by iterated Function System (IFS). This reduces the single-element antenna area by 24.88%. The dimension of proposed compact MIMO antenna is 44×44 mm2and its impedance bandwidth ranges (S11

  • parameter analysis of fractal image compression and its applications in image sharpening and smoothing
    Signal Processing-image Communication, 2013
    Co-Authors: Jianji Wang, Nanning Zheng, Gang Zhou
    Abstract:

    In recent years, numerous fractal image compression (FIC) schemes and their applications in image processing have been proposed. However, traditional FIC ignores the importance of affine parameters in the iterated Function System (IFS) and affine parameters are kept invariant for a certain image in almost all of these schemes. By analyzing fractal compression technology in this paper, we show that the affine parameters in IFS can vary with different image quality measurements. A positive correlation exists between the image contrast of fractal decoded image and affine scalar multiplier. This strong correlation demonstrates that an image can be sharpened or smoothed using fractal compression technology.
