The performance of a dual-arm millimeter wave Archimedean spiral antenna integrated on SOI is described. The impact of the feeding structure on the return loss and the axial ratio is displayed. A good return loss with 35 GHz -10 dB bandwidth and good circular polarization over 120° elevation angle independent on the azimuth angle (less than -5 dB axial ratio) are obtained. The simulated efficiency is 80 % with a gain of 4.3 dBi.
