Abstract :
This contribution presents a twoarm archimedean spiral antenna with a simple planar external feeding structure. Therefore this antenna can be integrated conformally into existing surfaces of vehicles, for example. The feeding structure shows an input impedance bandwidth of more than 10:1. Applications are in the area of broadband communications and navigation for mobile users as the antenna shows a non-directive pattern. Simulations and measurements demonstrate the principle of operation of this new type of antenna.
