1Volume of moving object
If conventional antennas are used in aerial vehicles, then data transmission can be achieved, but the antenna size is bulky and bandwidth is low
Solution Approach 1:
The patent transitions from conventional planar antenna structures to a three-dimensional stacked configuration with multiple layers (radiating patch layer, aperture layer, insulator layers, ground plane) separated by vertical distances. This dimensional change enables compact volume while maintaining or enhancing transmission performance through increased passive gain and bandwidth
Solution Approach 2:
The antenna design nests multiple functional layers within a compact structure, with the radiating patch layer, aperture layer, insulator layers, and ground plane arranged in a stacked configuration. Each layer contributes to the overall function while occupying minimal space, achieving high performance in a reduced volume
2Productivity
If conventional antennas are used, then basic communication is possible, but signal collisions occur and data capture is limited
Solution Approach 1:
The patent modifies key antenna parameters including the spacing between radiating patch and aperture layers (controlled by insulator thickness), the dimensions of the radiating patch, and the configuration of the ground plane. These parameter changes optimize the antenna for higher bandwidth operation and reduced signal loss, enabling improved data capture capability
Solution Approach 2:
The insulator layers serve as intermediaries between the radiating patch layer and aperture layer, and between the aperture layer and ground plane. These intermediate elements control the electromagnetic field distribution, reduce signal loss, and enable the antenna to achieve higher bandwidth and improved data transmission efficiency
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This antenna system enhances data transmission capabilities, reducing signal loss and enabling more efficient data collection and communication in aerial vehicle systems, particularly in unmanned aerial vehicles.
Implementation Method 1
The first insulator layer has a low dielectric constant and is sandwiched between the radiating patch layer and the aperture layer, thereby spacing the radiating patch and aperture layers apart from one another
Implementation Method 2
Other unmanned aerial vehicles may use antennas to transmit electromagnetic signals to detect a characteristic of the environment external to the vehicle

AI summary
An aerial device can be configured to fly above a route during movement of a vehicle along the route, such as for purposes of capturing image data of the route. The aerial device may include a microstrip antenna. The antenna includes a radiating patch layer, an aperture layer, a first insulator layer, a feed line, and a second insulator layer, all of which are parallel to and stacked on top of one another. The aperture layer is conductive and defines an aperture. The first insulator layer is sandwiched between the radiating patch layer and the aperture layer; thereby, the radiating patch layer and the aperture layer are spaced apart from one another by at least a thickness of the first insulator layer. The first insulator layer has a low dielectric constant. The second insulator layer is sandwiched between the aperture layer and the feed line.
