Abstract: This document describes techniques and systems for planar surface features for achieving antenna coverage. A structure is configured to provide a feed network for propagating electromagnetic energy along an energy path formed under a planar surface. The planar surface includes a recessed cavity with walls surrounding a cavity floor embedded within the planar surface. The cavity floor is shaped to form radiating slot(s) open through the structure to the energy path under the planar surface. A ridge feature protrudes from the planar surface on either side of the recessed cavity with a ridge length that is parallel with the cavity walls and a ridge height set to prevent cross-interference near the radiating slot within the cavity floor, thereby narrowing coverage for the electromagnetic energy within the feed network.

Abstract: This document describes trajectory planning in a three-dimensional (3D) search space with a space-time artificial potential field. An example system includes a processor that obtains an initial pose, a goal pose, and an obstacle map for an environment. The processor uses a parking trajectory algorithm to determine a trajectory by searching in a space-time artificial potential field. The trajectory includes a series of 3D waypoints, including two-dimensional (2D) positional coordinates and time coordinates, to navigate from the initial pose towards the goal pose. Operation of the host vehicle is then controlled to maneuver along the trajectory using an assisted-driving or autonomous-driving system. In this way, path searching is performed in the entire 3D search space rather than iterating between two 2D search planes. This allows motion planning for autonomous parking, especially with static and dynamic objects present, to determine an optimal trajectory in a single iteration.
