Abstract :
This paper proposes a novel ultra wideband (UWB) tapered slot antenna (TSA) to achieve both enhanced impedance bandwidth for UWB RF front-ends and band-stop characteristics in the 5 GHz WLAN band, limited by IEEE802.11a and HIPERLAN/2. To obtain these two characteristics of wideband and band-stop in the TSA, a broadband microstrip-slotline transition with multi-arm stubs and λ/4 short stubs are used respectively. From the measured results, it can be shown that a wide bandwidth of 1.99 octaves from 2.8 to 11.09 GHz for a VSWR<2 is obtained while the 5.0 ∼5.93 GHz band is rejected.
