Study Of A Novel C-Band Circular Slot Antenna Having Frquency Band-Notched Function
The Circular slot antenna is designed for C-Band(4Ghz-8Ghz) is suitable for mobile applications centre
frequency at 5 GHz. It contains 12 semicircular iteration section, each section is 1mm wide produce fringing effect. The
proposed antenna has a compact size, good radiation characteristics, wide band-width of 4.6 GHz to satisfy the requirement
of the current wireless communication systems. Antenna parameters like return loss(S11), gain, VSWR and radiation pattern
are calculated and simulated and compared. The design and simulation is done using HFSS v13 simulation tool and it is
fabricated on a FR4 Epoxy and RT duroid 5880 dielectric substrate.
