Abstract :
A second mode slot spiral antenna having maximum radiation between the broadside and horizontal directions is proposed for automotive applications. The antenna is situated in a shallow cavity and can be conformally mounted at various locations on a car. Finite element and fast multipole moment method simulations of the isolated and mounted antennas are provided and compared with measurements. It is shown that a 5.5 diameter aperture with 0.5 inch deep cavity can provide coverage for DAB, PCS and SDARS systems.
