AI Technical Summary
The existing antenna designs are not adaptable in the frequency range and have a large appearance, which affects the external design of the vehicle.
An ultra-wideband (UWB) antenna is designed, which includes a flat portion, a ground connection portion, a tapered portion and a circuit board. The tapered portion extends at least 40% about the periphery of the flat portion and extends from the feeder toward the ground plane, and as it moves away from the feeder, the height of the tapered portion decreases, and the lower edge is separated from the ground plane by a gap. The circuit board connects the feeder to the tapered portion and connects the circuit components to the ground plane.
The extremely low profile design of the antenna is realized, allowing it to be hidden in inconspicuous positions of the vehicle, improving the external design of the vehicle, and having extensive frequency adaptability.
