Abstract: Disclosed is a cross loop antenna system for an aerial vehicle. In one embodiment, the cross loop antenna system includes a cross bar antenna and a ground plane. The cross bar antenna includes two thin coplanar perpendicular bars that intersect in the middle and are parallel to the ground plane. Each bar couples to the ground plane at each end, comprising an antenna loop. Thus, the cross loop antenna system comprises two intersecting single-fed loops. The antenna can operate at a wavelength that is approximately twice the length of the bars. In such an embodiment, the antenna system may be resonant. The distance between the bars and the ground plane may be relatively small, thus minimalizing the vertical profile of the antenna. The antenna may be operated as a dual-band antenna and may produce an omnidirectional radiation pattern. An aerial vehicle may include two such antennas.

Abstract: Disclosed is a configuration for displaying a user interface on a device (e.g., a remote controller) to assist a user in correctly orienting the device for improved communication with an aerial vehicle. Position information is received by device from the aerial vehicle. The remote controller detects its own position and orientation. Based on the orientation of the remote controller and the relative position of the remote controller and aerial vehicle, the remote controller displays an indication to the user to assist the user in orienting the remote controller so that one or more directional antennas of the remote controller are oriented for effective communication between the device and the aerial vehicle. Also disclosed is an antenna configuration within a housing of a remote controller. The antenna configuration includes two ceramic patch antennas.
