Reconfigurable double slot-ring antenna for bandwidth enhancement
A reconfigurable single slot-ring antenna is able to switch between S and C bands using PIN diode switches. However, the fractional bandwidth of this single slot-ring antenna at lower band is narrow (11.4%). In this paper, four additional slots are added to form a double slot-ring antenna at the lower band. As a result, the antenna fractional bandwidth at the lower band is significantly enhanced from 11.4% to 28.2%, while the antenna performance at higher band is not compromised. Full-wave simulations show that the antenna efficiency is high and the radiation patterns do not change across each respective frequency band.
