Abstract
This paper describes the design of novel penta-band active integrated spiral antenna for vehicular wireless applications. Frequency transformation method is adopted for the input matching network of the penta band low noise amplifier (LNA) and by using load-pull methodology; the output matching circuit is designed with simple LC matching network. The designed active integrated spiral antenna operates at navigational frequencies 1.32/1.5 GHz, wireless communication frequencies 2.4/3.3 GHz and Dedicated short range communication frequency 5.8 GHz.
