Loop Antenna Asymmetric Intersection for Noise Reduction

The patent applies asymmetry by intentionally introducing an asymmetric defect at the intersection part of the loop antenna. Specifically, the continuous conductive wiring is made asymmetric with respect to the center line at the intersection, creating an asymmetric current distribution that cancels out the symmetric electromagnetic noise components, thereby reducing overall noise emission while maintaining wireless power transmission capability.

The patent changes the structural parameter of the loop antenna by introducing a defect at the intersection part. This parameter change (creating an asymmetric gap or discontinuity) fundamentally alters the current distribution pattern from symmetric to asymmetric, which in turn changes the electromagnetic radiation characteristics and reduces noise generation.

The patent enhances the noise reduction effectiveness by deliberately introducing asymmetric defects at the intersection parts of the loop antenna. This asymmetric design creates specific current distribution patterns that more effectively cancel electromagnetic noise compared to conventional symmetric loop antennas, thereby improving noise reduction reliability.

The patent applies local quality by making only the intersection parts asymmetric while keeping other parts of the loop antenna symmetric. This localized asymmetric defect is strategically placed to maximize noise cancellation effectiveness without compromising the overall antenna structure or wireless power transmission function.

The patent resolves this contradiction by making the intersection parts asymmetric. When the loop-shaped member is wound multiple times, intersection parts are inevitably created. By introducing asymmetric defects at these intersections, the patent maintains the high antenna efficiency provided by multiple windings while simultaneously reducing the electromagnetic noise generated at the intersection points.

The patent applies local quality by treating the intersection parts differently from the rest of the antenna structure. While the majority of the loop maintains its continuous conductive structure for efficiency, the intersection parts are specifically modified with asymmetric defects to address noise generation, thus optimizing both efficiency and noise reduction locally.
