Two-arm Archimedean spiral antenna fed by broadband double sided parallel strip line.

ABSTRACT This paper is intended to introduce a two-arm Archimedean spiral antenna fed by a novel feed structure based on DSPSL (Double Sided Parallel Strip Line). A DSPSL provides an ease perpendicular matching network and an impedance transition between input impedance of a spiral antenna and system's impedance of 50 Ω in broadband frequency range. Measured and simulated VSWR and radiation pattern results show a good performance over ultra-wide band from 2 to 20 GHz. © 2016 Wiley Periodicals, Inc.
