Abstract :
The original ultra-wideband impedance transformer providing the required electromagnetic matching of the coaxial cable with the dual-arm spiral antenna is proposed. The calculated input reflection coefficient of the spiral antenna with transformer is less than -10dB within the frequency band from 10GHz to 110GHz.
