Abstract :
A new broadband slot antenna with low cross-polarization is presented. It is realized by introducing metal stubs in the aperture of a conventional bow-tie slot antenna. A spectral domain moment method analysis shows that the cross-polarization can be reduced by about 15 dB. The SWR remains below 1.6 in the bandwidth fupper/flower=2.8. Experimental data are in good agreement with theoretical predictions.
