Engineering Contradiction Analysis
1Power
If 3D transmitter antennas are used to achieve high gain in small areas for remote wireless charging, then wireless power transmission capability is improved, but antenna dimensions (depth) increase making them aesthetically unappealing
Solution Approach 1:
The patent embeds the resonator element inside a ceramic substrate, creating a nested structure where the active antenna component is contained within a compact housing. This allows the antenna to achieve high gain while maintaining a shallow profile suitable for wall mounting in consumer environments.
Solution Approach 2:
The patent uses a ceramic substrate with high relative permittivity (dielectric constant) to reduce the physical dimensions of the antenna while maintaining its electrical performance. By changing the dielectric parameter of the substrate material, the antenna achieves high gain in a more compact form factor.

If resonator element dimensions are reduced to improve aesthetics, then antenna compactness is improved, but wireless signal radiation capability deteriorates
Solution Approach 1:
The patent compensates for the reduced physical size of the resonator element by using a ceramic substrate with high relative permittivity. This material parameter change allows the smaller resonator to maintain its wireless signal radiation capability by concentrating the electromagnetic field more effectively.
Solution Approach 2:
The patent combines the resonator element with a ceramic substrate to create a composite antenna structure. The ceramic material provides the necessary dielectric properties to enhance the radiation capability of the compact resonator, allowing small dimensions without sacrificing power transmission capability.
