Abstract
In this paper a novel band notch antenna in UWB frequency range is designed using split rings. Split rings are overlapped with designed monopole to give phi shape. The slit gap gives band-notch operation from 5.1GHz to 6.29GHz and from 4.94GHz to 5.91GHz for SPSSR and SPSCR antennas respectively. Simulated and measured results are in good agreement.
Highlights
For a wireless communication system, large bandwidth is an important requirement
Initial antenna design is done for split Phi shape square ring (SPSSR) antenna and is applied to split Phi shape circular ring (SPSCR) antenna by using the same optimised dimensions, because of this there may be a slight mismatch in input imedence of SPSCR comapred to SPSSR antenna and results are not exactly matching with each other
A novel SPSSR antenna is designed and the same design is applied to SPSCR antenna in UWB frequency range
Summary
For a wireless communication system, large bandwidth is an important requirement. UWB antenna gives large bandwidth of 7.7GHz (3.1GHz to 10.6GHz), it faces many challenges of interference with existing systems in UWB range. In this paper a novel band notch antenna is designed by merging a monopole antenna with a square or circular split ring resonator This proposed antenna shape looks like the Greek letter Phi (φ) is named as split Phi shape square ring (SPSSR) antenna and split Phi shape circular ring (SPSCR) antenna. The band-notched characteristics are obtained by adding a stepped impedance resonator (SIR) or a split ring resonator (SRR) on the feed line or cutting slots in the ground plane [7, 8]. A bandnotch antenna is designed by etching a nested CSRR inside the ground plane in [9] Another technique to obtain band-notch characteristics is by adding the parasitic elements in the form of printed strips placed in the radiating aperture of the planar antenna at the top and bottom layer. Results show acceptable discrepancy between simulation and measurement due to the influence of the SMA connector for testing and the indoor measurement environment
