Abstract: Multi-band antenna for use with limited size ground planes. In one embodiment, the multi-band antenna includes a substrate having a first radiator branch and a second radiator branch; a first switch that is connected with the first radiator branch and a radio module; and a second switch that is connected with the second radiator branch and matching circuitry. Selection between different states of the first switch and the second switch enable the multi-band antenna to operate in a plurality of operating bands. These operating bands may include both the high and low frequency bands for a long-term evolution (LTE) communication device as well as a global navigation satellite system (GNSS) frequency band. Methods of operating the multi-band antenna as well as systems that incorporate the multi-band antenna are also disclosed.

Abstract: A LIDAR apparatus includes an emitter array having a plurality of emitter pixels configured to emit optical signals, a detector array having a plurality of detector pixels configured to output detection signals responsive to light incident thereon, and a circuit that is coupled to the detector array. The circuit is configured to perform operations including receiving the detection signals output from the detector array, where each of the detection signals includes component measurements defining a respective phase vector, generating a combined vector based on the component measurements of a plurality of the detection signals, and identifying a distance range of a target from which the optical signals were reflected based on an angle of the combined vector. Related devices and methods of operation are also discussed.
