| Popis: | A proximity-fed annular slot antenna for UWB applica- tions with a band rejection using difierent techniques is presented. The proposed antenna provides an UWB performance in the frequency range of … 2:84 to … 8:2GHz with relatively stable radiation parame- ters. Three difierent techniques to construct a resonant circuit for the proposed antenna are investigated to achieve the band-notch property in the band … 5:11 to … 5:69GHz band which include the WLAN and HIPERLAN/2 services without degrading the UWB performance of the antenna. Three resonators are considered; a single complementary split ring resonator (CSRR), a complementary spiral loop resonator (CSLR) and a spurline slot. Furthermore, the band-notched resonance frequency and the bandwidth can be easily controlled by adjusting the dimensions of the resonator. The proposed antenna is simulated, fab- ricated and measured. The measured data show very good agreements with the simulated results. The proposed antenna provides almost om- nidirectional patterns, relatively ∞at gain and high radiation e-ciency over the entire UWB frequency excluding the rejected band. |
