The present invention discloses a dual-band microstrip antenna and an unmanned aerial vehicle using same. The dual-band microstrip antenna includes: a substrate; a first-band microstrip antenna, disposed on a front surface of the substrate and configured to generate first-band resonance; a second-band microstrip antenna, disposed on a back surface of the substrate and configured to generate second-band resonance and high-order resonance of the second-band resonance, the high-order resonance of the second-band resonance being used to be superposed on the first-band resonance; and a coaxial feeder, configured to feed the first-band microstrip antenna and the second-band microstrip antenna. By means of embodiments of the present invention, the beamwidth of the dual-band microstrip antenna on a pitch surface at first-band resonance can be expanded, so that a stable signal can be kept when the antenna tilts.

An aerial vehicle capable of convertible flight from hover to linear flight includes a body having a longitudinal body axis, a plurality of forward wings, a plurality of aft wings, at least one motor, and at least three aerodynamic propulsors driven by the at least one motor. Each forward wing extends a forward wing plane. Each aft wing extends from an aft wing plane. The aerodynamic propulsors are mounted longitudinally between the plurality of forward wings and plurality of aft wings.

A parallel manipulator with six degrees of freedom may include a base that attaches to a unmanned aerial vehicle and a movable gripper element that may be positioned below the UAV. The positioning of the gripper element my reduce impact of the center of gravity of the attached UAV. The gripper element may include a geometric shape that complements objects routinely used in high-throughput screening (HTS) laboratories, such as microplates. The parallel manipulator and gripper element may be used to quickly, safely, and securely move objects in HTS laboratories and/or the like.

Landing pads for a drone. One of the landing pads can include a landing area with a first surface configured to receive a second surface of a landing gear of a drone; a docking area i) with a first end adjacent to the landing area and a second opposite end and ii) a docking surface configured to contact the second surface of the landing gear of the drone; a fixed member i) with a third surface adjacent to the second end of the docking area and ii) configured to contact an end of the landing gear of the drone; a moveable member configured to i) move the landing gear across the first surface of the landing area onto the docking surface and ii) secure the landing gear of the drone in place between the docking surface of the docking area and the third surface of the fixed member.

A dropping mechanism with universal mounting points includes a device for securing a payload to a drone, mechanically releasing it and mounting additional accessories that can be used during flight. The dropping mechanism can be attached to either the landing gear or body of the drone, in an orientation that allows contact between the release trigger and the drone's camera. A notch and groove system holds a sliding restraint in place, keeping the payload secure during flight. Once the release trigger is pushed, an energized member pulls the sliding restraint allowing the payload to drop. Since the camera is pointed down to actuate the trigger, the user can watch as the payload falls to the ground. The use of a mechanical dropping system makes this device compatible with drones that only have an electrical connection for the camera. Universal mounting points allow attachment of a wide variety of accessories.

Various embodiments include methods of navigating a drone that may include determining whether a radio link quality trigger event associated with communications with the drone has occurred while the drone travels along a set route to a destination. The radio link quality trigger event may correspond to predetermined characteristics of radio link quality. The drone may be steered to follow a search maneuver for improving radio link quality in response to determining the radio link quality trigger event has occurred. The search maneuver may follow a preconfigured deviation pattern that is configured before determining whether the radio link quality trigger event has occurred and departs from the set route.

Systems, devices, and methods for a ground support system for an unmanned aerial vehicle (UAV) including: at least one handling fixture, where each handling fixture is configured to support at least one wing panel of the UAV; and at least one dolly, where each dolly is configured to receive at least one landing pod of the UAV, and where each landing pod supports at least one wing panel of the UAV; where the at least one handling fixture and the at least one dolly are configured to move and rotate two or more wing panels to align the two or more wing panels with each other for assembly of the UAV; and where the at least one dolly further allows for transportation of the UAV over uneven terrain.

The flying vehicle in this invention has landing legs with a grounding part, the grounding part being shaped such that the drag force decreases during traveling rather than during landing. The shape of the grounding part is substantially wing-shaped in the front-rear direction of the airframe, and the angle of attack of the grounding part is reduced when the flying vehicle moves forward than when it lands. The grounding part has an inverted wing shape in the longitudinal direction of the airframe, and the angle of attack of the grounding part is reduced during travel rather than during landing. A plurality of landing legs are provided, and the grounding part of the shape is provided only on the landing leg on the forward side of the airframe. The landing legs are connected to the grounding part and provided with an intermediate member extending at least vertically, and the structure of the grounding part is more fragile than the intermediate member.
