Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ceramic base body is used in the ceramic patch antenna structure, then the signal transmission function is achieved, but the base body is easily fractured by external force causing disconnection of the signal feeding body
Solution Approach 1:
The patent applies composite materials by combining ceramic material (providing high dielectric constant for signal transmission) with resin material (providing fracture resistance). The base body is formed as a composite structure where the ceramic material constitutes 30-70% by volume, creating a material that maintains electromagnetic properties while resisting external force and preventing disconnection of the signal feeding body.
2Reliability
If a pure ceramic base body is used, then the dielectric constant is high for good signal transmission, but the weight is heavy
Solution Approach 1:
The patent uses composite materials consisting of ceramic material and resin material, where the ceramic content is controlled at 30-70% by volume. This composition maintains sufficient dielectric constant for signal transmission while the resin component reduces the overall density and weight of the base body, achieving a balance between electrical performance and weight reduction.
Solution Approach 2:
The patent applies local quality by strategically distributing ceramic and resin materials within the base body. The ceramic material is positioned to ensure adequate dielectric properties in critical signal transmission zones, while resin material is distributed to reduce weight in non-critical areas, optimizing the local material properties to achieve both signal quality and weight reduction.

AI summary
The invention provides a ceramic patch antenna structure which comprises a composite material base body, a radiation metallic layer, a grounding metallic layer and a signal feeding element. The composite material base body is composed of a high dielectric constant (K) material and a low K material, having a front surface, a rear surface and a through hole. The radiation metallic layer is provided on the front surface of the composite material base body. The grounding metallic layer is provided on the rear surface of the composite material base body. The signal feeding element has a head thereon, the head has a shaft extending from the bottom thereof and the shaft has a projection on a surface thereof. As the signal feeding element is screwed to the through hole, the projection of the shaft destroys an internal wall of the through hole to latch in the through hole.
