Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Antenna devices in the mmWave band face challenges in securing both horizontal and vertical polarized components due to limitations in extending the radiating body length in the vertical direction on a multiple layer circuit board, which affects coverage and data transmission.
Innovation Solution
A mixed polarized antenna device is designed with a first radiating body on the side surface of the circuit board and a second radiating body extending vertically, accompanied by a reflector and dielectric material to enhance vertical polarization, while maintaining the board's thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the radiating body is extended in the vertical direction to secure vertical polarization component, then the vertical polarized component can be secured, but the thickness of the multiple layer circuit board must be increased
Solution Approach 1:
The patent transitions from a planar radiating body configuration to a three-dimensional structure by adding a vertical radiating body that extends perpendicular to the circuit board surface. This dimensional change enables vertical polarization without increasing the board's thickness, as the radiating element projects outward in the Z-direction rather than requiring additional board layers.
Solution Approach 2:
The vertical radiating body is integrated with the existing circuit board structure, where the radiating body is mounted on or embedded within the board's surface features. This nesting approach allows the vertical element to be accommodated within the existing form factor while adding the necessary polarization capability.
2Volume of moving object
If the radiating body length is kept short to maintain compact size, then the device remains compact, but the antenna cannot support mmWave band communication effectively
Solution Approach 1:
The patent achieves the required effective radiating length for mmWave operation by extending the radiating body in the vertical dimension rather than increasing its planar footprint. This allows the antenna to achieve the necessary electrical length (λ/4 to λ/2 at mmWave frequencies) while maintaining a compact overall device volume.
Solution Approach 2:
The patent changes the geometric parameters of the radiating body, specifically its orientation and dimensional distribution, to achieve the required electrical characteristics for mmWave operation. By configuring the radiating body with appropriate length and orientation in three-dimensional space, the antenna achieves resonance at mmWave frequencies without requiring a large physical size.
