A NOVEL PLANAR UWB MONOPOLE ANTENNA WITH VARIABLE FREQUENCY BAND-NOTCH FUNCTION BASED ON ETCHED SLOT-TYPE ELC ON THE PATCH

摘要

A novel planar ultra-wideband (UWB) monopole antenna with variable frequency band-notch characteristic is proposed and investigated for UWB communication applications. The complementary electric-LC (CELC) resonator is etched inside the circular patch of the monopole antenna to achieve notch frequency band. The designed antenna satisfies the voltage standing wave ratio (VSWR) requirement of less than 2.0 in the frequency band between 2.8 and 12.6 GHz, while showing the WLAN band notched in the frequency band of 5-5.9 GHz.
