Analysis and Design of a Multiband, Multipolarized Two Arm Sinuous


Michael C. Buck and Dejan S. Filipović

Department of Electrical and Computer Engineering

A computational study and design of a two-arm printed sinuous antenna is presented. Most research on sinuous antennas has been limited to geometries with at least four arms for use in applications requiring broadband and dual orthogonally polarized performance. However, we have shown that while achieving broadband performance from a two-arm sinuous antenna is roblematic, it is possible to achieve multiband and multipolarized operation with good axial ratio (AR < 3 dB) and azimuthal pattern symmetry (WoW3dB < 3 dB) over several bands with opposite polarization between the neighboring bands.
