Signal Integrity Analysis of High Speed Interconnects In PCB Embedded with EBG Structures
Sindhadevi, M.,Kanagasabai, Malathi,Arun, Henridass,Shrivastav, A. K. The Korean Institute of Electrical Engineers 2016 Journal of Electrical Engineering & Technology Vol.11 No.1
This paper brings out a novel method for reducing Near end and Far end Crosstalk using Electromagnetic Band Gap structures (EBG) in High Speed RF transmission lines. This work becomes useful in high speed closely spaced Printed Circuit Board (PCB) traces connected to multi core processors. By using this method, reduction of −40dB in Near-End Crosstalk (NEXT) and −60 dB in Far End Crosstalk (FEXT) is achieved. The results are validated through experimental measurements. Time domain analysis is performed to validate the signal integrity property of coupled transmission lines.

Compact and Flexible Monopole Antenna for Ultra-Wideband Applications Deploying Fractal Geometry
Geetha G,Sandeep Kumar Palaniswamy,M. Gulam Nabi Alsath,Malathi Kanagasabai,T. Rama Rao 대한전기학회 2018 Journal of Electrical Engineering & Technology Vol.13 No.1
This paper presents a compact ultra-wideband (UWB) flexible monopole antenna design on a paper substrate. The proposed antenna is made of iterations of a circular slot inside an octagonal metallic patch. This fractal-based geometry has been deployed to achieve compactness along with improved bandwidth, measured reflection coefficient -10 ㏈ bandwidth ranging from 2.7 to 15.8 ㎓. The overall size of the antenna is 26 ㎜×19 ㎜×0.5 ㎜, which makes it a compact one. The substrate used is paper and the main features like environment friendly, flexibility, green electronics applications and low cost of fabrication are the key factors for the proposed antenna. The aforementioned UWB prototype is suitable for many wireless communication systems such as WiMAX, WiFi, RFID and WSN applications. Antenna has been tested for the effect of bending by placing it over a curved surface of a very small radius of 10 ㎜.
