Abstract: An antenna system includes: a first patch antenna element that is electrically conductive; a first energy coupler configured to convey first energy to, or receive the first energy from, the first patch antenna element, the first energy being in a first frequency band; a second patch antenna element at least partially overlapping the first patch antenna element, the second patch antenna element comprising a plurality of physically separate portions that are each electrically conductive; and a second energy coupler connected to a first subset of the plurality of physically separate portions, the first subset comprising less than all of the plurality of physically separate portions, the second energy coupler configured to convey second energy to, or receive the second energy from, the first subset, the second energy being in a second frequency band that is higher than the first frequency band.

Abstract: An antenna system includes: a first patch antenna element that is electrically conductive; a first energy coupler configured to convey first energy to or from the first patch antenna element; a second patch antenna element at least partially overlapping the first patch antenna element, the second patch antenna element defining a first slot through the second patch antenna element; and a second energy coupler configured to convey second energy to, or receive the second energy from, the first slot or a first dipole at least partially overlapping the first slot.

Abstract: A scanning device generally produces an image having a uniform resolution throughout a target region. To improve radar scanning/lidar scanning, an efficient scan approach to enable a radar device/lidar device to adoptively perform a scan of a target region based on interested regions and/or an adjustable resolution. The apparatus may be a scanning device for scanning. The apparatus performs a first scan over a target region to obtain a plurality of first scan samples at a plurality of locations within the target region. The apparatus generates a saliency map of the target region based on signal intensities of the plurality of first scan samples. The apparatus determines a salient region within the target region based on the saliency map. The apparatus performs at least one second scan over the salient region to obtain at least one second scan sample in the salient region.

Abstract: An antenna is described. The antenna includes a planar circular structure. The antenna also includes a radiating element located at the center of the planar circular structure. The antenna further includes one or more parasitic elements located on a contour around the radiating element. The parasitic elements are aligned in parallel direction with the radiating element. The parasitic elements protrude from the planar circular structure. The antenna includes switches separating each of the one or more parasitic elements from ground. A switch in a first position creates a short between a parasitic element and ground. A switch in a second position creates an open circuit between the parasitic element and ground.
