Innovation Solution
A terminal housing with a reconfigurable antenna design that includes a bottom metal bezel with slits, a main board unit with a switching module, and an antenna unit with multiple branches, allowing the switching module to control the formation of either a dual PIFA or PIFA composite dual LOOP antenna architecture, thereby expanding the radiation frequency band and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional antenna design is used in limited terminal space, then the antenna structure is simple, but the radiation frequency bandwidth is limited and communication performance deteriorates
Solution Approach 1:
The patent implements a reconfigurable antenna system where the antenna structure can dynamically change its configuration between PIFA and LOOP modes through a switching module. This dynamic reconfiguration allows the antenna to adapt to different frequency bands (e.g., 700MHz, 800MHz, 900MHz, 1800MHz, 2100MHz, 2600MHz) without requiring multiple fixed antenna structures, thereby resolving the contradiction between bandwidth adaptability and structural complexity.
Solution Approach 2:
The patent designs a single antenna structure that can perform multiple functions by switching between PIFA and LOOP configurations. The same physical antenna elements (horizontal bezel, first branch, second branch, third branch, fourth branch) can serve different radiation purposes across multiple frequency bands, eliminating the need for separate antennas for each frequency band and reducing overall device complexity while enhancing versatility.
2Adaptability or versatility
If multiple antennas are used to cover different frequency bands, then the radiation frequency bandwidth is improved, but the terminal space requirement increases
Solution Approach 1:
The patent merges multiple antenna functions into a single reconfigurable antenna system. By combining the PIFA and LOOP antenna capabilities in one structure that can switch between configurations, the patent achieves multi-frequency band coverage without requiring separate physical antennas for each band, thereby maintaining frequency band coverage while minimizing the use of terminal empty space.
Solution Approach 2:
The dynamic switching capability allows one physical antenna structure to assume different electrical configurations for different frequency bands. The switching module enables the antenna to transform between PIFA and LOOP modes, allowing a single antenna to replace what would traditionally require multiple fixed antennas, thus saving terminal space while maintaining comprehensive frequency band coverage.
3Productivity
If antenna components are placed close to other terminal components, then the terminal structure is compact, but antenna performance deteriorates due to interference
Solution Approach 1:
The patent segments the antenna structure into distinct functional branches (first branch, second branch, third branch, fourth branch) that can be independently controlled through the switching module. This segmentation allows selective activation of different antenna paths depending on the required frequency band, enabling the antenna to maintain optimal radiation performance even when integrated closely with other terminal components by activating only the necessary antenna segments for each communication scenario.
