Low Profile Tri-Axial Antenna Quadrant Core Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional low profile triaxial antennas face a trade-off where increasing the capacity of X-axis and Y-axis windings reduces the Z-axis winding's emission and reception capacity, making it impossible to reduce thickness without compromising capacity.
Innovation Solution
Incorporating four electromagnetic core portions in the quadrant spaces between the X-axis, Y-axis, and Z-axis windings, which collaborate with the Z-axis winding to enhance its capacity by up to 30%, while maintaining the antenna's low profile configuration without reducing X-axis and Y-axis capacities, using a composite electromagnetic core that includes a cross-shaped core and additional core portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the length of the four intersecting arms of the cross-shaped electromagnetic core is increased to increase the capacity of the X-axis and Y-axis windings, then the emission and reception capacity of the Z-axis winding is reduced as the Z-axis winding moves away from the central mass
Solution Approach 1:
The electromagnetic core is divided into a cross-shaped core and four separate electromagnetic core portions positioned in the quadrant spaces. This segmentation allows the X-axis and Y-axis windings to maintain their capacity through the cross-shaped core while the four core portions are strategically placed to enhance the Z-axis winding's capacity without increasing overall thickness.
Solution Approach 2:
The solution transitions from a two-dimensional cross-shaped core to a three-dimensional configuration by adding four electromagnetic core portions in the quadrant spaces between the arms. This dimensional enhancement allows the Z-axis winding to have closer proximity to magnetic material without increasing the antenna's thickness, thereby improving Z-axis capacity while maintaining low profile.
2Length of stationary object
If the thickness is reduced to achieve a low profile configuration, then the emission and reception capacity is compromised
Solution Approach 1:
The four electromagnetic core portions are strategically positioned in the quadrant spaces where they are most needed to enhance the Z-axis winding's capacity. This localized enhancement allows the antenna to maintain low overall thickness while concentrating magnetic material where it provides the greatest benefit to Z-axis performance.
Solution Approach 2:
The four electromagnetic core portions are nested within the quadrant spaces formed by the cross-shaped core's arms, utilizing the existing structural voids. This nesting approach adds functional magnetic material without increasing the antenna's external dimensions or thickness, thereby improving capacity while maintaining low profile.
3Reliability
If all magnitudes of the antenna are scaled up to increase emission and reception capacity, then volume and weight increase
Solution Approach 1:
The invention changes the distribution and configuration parameters of the electromagnetic core rather than simply scaling up all dimensions. By repositioning magnetic material into the quadrant spaces and optimizing the arrangement of core portions, the antenna achieves enhanced capacity with the same or reduced overall volume.
