Design of Ultra Wideband Antenna Matching Networks: via Simplified Real Frequency Technique (SRFT) opens new horizons for design engineers, researchers, undergraduate and postgraduate students to build a multi-band and ultra wideband antenna matching network for the antenna which in turn will push the edge of technology to produce a new generation of complex communication systems at microwave frequencies well outside the line of commercial and military. In the design of Ultra Wideband Antenna Matching Networks, many real-life examples are presented for designing matching networks for HF antennas and commercial cellular multi-band frequency.
