Notched Circular EBG based Circularly Polarized Antenna for Performance Enhancement

In this article, a novel Compact Circularly Polarized Antenna with notched circular Electromagnetic Band Gap (NCEBG) structure is put forward. This proposed comprises of truncated rectangular patch antenna having its ground plane defected by slots etched on it to achieve compactness and wide impedance bandwidth. structures have the attractive feature in-phase reflection stopband creation for surface waves, enabling waves be suppressed; this, in turn, leads enhanced performance when loaded such structures. For enhancing functioning regard bandwidth, axial ratio bandwidth gain, seven NCEBG's are substrate which surrounds patch. Additionally, research exhibits low profile 0.473 λo x 0.039 (λo at center frequency 7.46GHz represents free space wavelength). The measured outcomes prototype-fabricated match well results simulation, showing 3-dB 13.66% an 73.29% peak gain 7.32dBi operating band. improved marks as favorable applicant wireless communication techniques thus finding application various ways.
