Abstract :
In this paper, novel ultra-wideband flexible step-impedance spiral antenna (SIA) is proposed. Proposed antenna has VSWR<;2 frequency range between 10.5 GHz and 57 GHz. In comparison with conventional an Archimedean spiral antenna with constant line width, proposed antenna has an excellent impedance matching, better directivity and radiation efficiency in the entire operating range.
