Abstract :
A new planar monopole UWB antenna with CPW-fed and sharp band notch characteristics is proposed. To suppress interference from the WLAN system, a tuning stub is inserted in the planar antenna and a frequency band notch function is thus created in the WLAN frequency range. The antenna offers an excellent operating frequency range from 2.35 GHz to 13 GHz (VSWR≤-2), and possesses band notch from 4.9 GHz to 5.92 GHz (VSWR>;2). The radiation patterns of the antenna are illustrated with the electromagnetic simulation Software HFSS, and the results indicate the design is reasonable.
