ABSTRACT: As per the entail in
wireless communication, the ever increasing switching speeds of digital devices
pose significant challenges. Signal quality is more important for high speed
products and thesignal integrity
must ensure reliable transmission where signal integrity is a measure of the
quality of an electrical signal. A high speed differential signal will result
in signal integrity issues such as crosstalk and radiated emission. One of the
solutions to suppress radiated emission is defected ground pattern. This paper
introduces a novel trident incurvature shaped defected ground structure to
suppress radiated emission that arises in high speed differential signal.The proposed defected ground structure
is implemented using Ansoft HFSS simulation tool and its performance isquantified in terms of scatteringparameters. The proposed trident
incurvature shaped defectedground
pattern reduces near endcoupling
and far end coupling by more than 6 dB and 2 dB respectively. It also provides
better return loss and insertion loss in the frequency range 1 - 6 GHz.
