Abstract:
UWB is a radio communication technology
that utilizes very low energy pulses and is intended for
short-range-cum-high-bandwidth communications by
using an enormous portion of radio spectrum. UWB is
very high speed alternative to existing wireless
technologies such as WLAN, Hyper-LAN. Compact
planar ultra-wideband (UWB) printed microstrip
patch antennas with dual band notch attribute is
structured in this paper. The antenna has total
dimensions of 21.8x24.1 mm 2 , which is well suited with
wireless devices. The proposed antenna comprises of
chamfered rectangular radiating patch along with partial
ground to boost bandwidth that covers the UWB
frequency range from 2.5 GHz-11 GHz. A Quarter
wave transformer along with feed line is used for
impedance matching. To obtain dual notch
characteristics at C-band (3.3 GHz-3.9 GHz) and X-
band (7.4 GHz-8.8 GHz), a complementary split ring
resonators (CSRR) is used in partial ground and
patch both. The impacts of ringson band notch
characteristics are also examined. All simulation work
has been completed by utilizing electromagnetic
software Ansoft High Frequency Structure Simulator
(HFSS).
