Abstract
A new modified compact microstrip line-fed Ultra-Wide Band
(UWB) tapered- shape antenna with WLAN (5.5GHz) band
notch function using inverted C-slot is presented. The overall
antenna dimensions are 22x24 mm2
fabricated on FR4 substrate
with a thickness h of 1.5mm and a relative permittivity εr
of 4.5
and easily fed by a 50Ω microstrip line. A complete analysis on
the inverted C-slot was simulated and measured. The modified
antenna is successfully fabricated and measured. Simulation and
measurements agree that the modified antenna has a stable gain,
high radiation efficiency(about 90%), and near omni-directional
radiation pattern within the UWB operating frequency range
while a good characteristics are obtained at the specified notch
with a low gain of -4.2dB and VSWR of 6.3 .
