Abstract

Development of wireless technologies pushes for more accurate and more consistent EMC measurements. Antenna cross polarization is found to be a main contributor to the measurement errors. In this paper, full-wave analysis of E-field distribution of various slotlines is presented, which reveals that the bilateral tapered slot antenna has the widest impedance bandwidth and the lowest cross-polarization level simultaneously. The conclusions obtained in this paper will be used to develop an innovative wideband (from 700 MHz to 20 GHz) bilateral tapered slot antenna used for wireless EMC testing.
