Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna structures in electronic devices face challenges in configuring multiple wireless signal transmission within limited space due to interference between different frequency bands, making it difficult to optimize the layout of antennas and other electronic elements.
Innovation Solution
The antenna structure employs two closely disposed transmitting elements with specific L-shaped connecting and radiation portions, optimized in size and gap configuration to reduce interference and allow transmission of four different wireless signals, thereby simplifying the internal configuration and reducing the overall antenna size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antenna structures are separated to reduce interference, then signal transmission quality is improved, but device space utilization deteriorates
Solution Approach 1:
The patent combines multiple antenna structures (WWAN antenna and WLAN antenna) into a single integrated antenna structure. The first transmitting element and second transmitting element are disposed in close proximity sharing a common ground element, enabling multiple wireless signals to be transmitted through one unified structure rather than separate antennas, thus improving space utilization while maintaining signal quality through careful design of the transmitting elements and gaps between them
Solution Approach 2:
The patent applies different design characteristics to different parts of the antenna structure. The first transmitting element and second transmitting element have different dimensions and are positioned at specific locations with controlled gaps between them. The ground element is divided into multiple portions with specific gap configurations. This local differentiation allows each region to optimize for its specific frequency band while the whole structure remains compact
2Volume of moving object
If antenna size is reduced to fit limited space, then device compactness is improved, but signal transmission capability deteriorates
Solution Approach 1:
The patent transitions from conventional single-plane antenna designs to a multi-dimensional structure. The first and second transmitting elements are disposed in different spatial arrangements with specific gap configurations in multiple directions. The ground element portions are positioned at different heights and locations, creating a three-dimensional antenna structure that achieves compact volume while maintaining effective signal transmission capability across multiple frequency bands
Solution Approach 2:
The patent implements a nested configuration where the second transmitting element is positioned within the spatial envelope defined by the first transmitting element. The smaller second transmitting element with its ground element portion is nested among the larger first transmitting element structure, allowing both elements to coexist in a compact volume without significant interference, thus reducing overall antenna size while maintaining transmission capability

AI summary
An antenna structure includes a ground element, a first transmitting element and a second transmitting element. The first transmitting element transmits a first wireless signal, and comprises a first connecting portion and a first radiation portion. The first connecting portion is connected to the ground element and the first radiation portion. The second transmitting element transmits a second wireless signal and comprises a second connecting portion and a second radiation portion. The second connecting portion is connected to the ground element and the second radiation portion. The second connecting portion is shorter than the first connecting portion, and the second radiation portion is shorter than the first radiation portion.
