| Abstract: | A microstrip fed ultra-wideband tapered slot antenna is designed and fabricated. The wideband impedance matching is obtained by the use of a modified microstrip/slotline transition. The improvement of impedance characteristics at the lower band is achieved by introducing a novel flare curve as a radiation part. The measured results of the proposed antenna demonstrate that this directional antenna achieves a ratio bandwidth of 15.4∶1 for VSWR≤2 from 0.92 to 14.25GHz. The front-to-back ratio and cross polarization ratio of its radiation patterns over the operating band are greater then 18 dB and less than -18dB, respectively. |
