Abstract
A wideband spiral antenna system for a vehicle is provided. A planar spiral antenna is fabricated on a substrate. The planar spiral antenna includes an antenna feed. A first dielectric panel is disposed adjacent to a first side of the substrate. A dielectric puck has a first puck side disposed adjacent to the antenna feed on a second side of the substrate opposing the first side of the substrate. A radio frequency (RF) connector is disposed adjacent to a second puck side of the dielectric puck. The second puck side opposes the first puck side of the dielectric puck. One or more conductive vias extend from the antenna feed through the dielectric puck to the RF connector electrically coupling the antenna feed to the RF connector.
