Engineering Contradiction Analysis
1Volume of moving object
If a planar antenna uses a flexible base board to achieve thinness and space saving, then the antenna structure becomes compact and adaptable, but the base board deforms easily under external forces affecting signal reception quality
Solution Approach 1:
The antenna oscillator is divided into multiple independent frequency band oscillators (UHF and VHF bands) arranged on the flexible base board. Each oscillator is structurally segmented with support connections to the base board, allowing the antenna to maintain compactness while distributing mechanical stress across multiple segments rather than a single continuous structure, thereby reducing deformation impact on signal reception.
2Reliability
If the antenna oscillator layout is optimized for signal reception, then signal receiving ability improves, but the structural strength of the base board is not enhanced
Solution Approach 1:
The antenna design merges the functional oscillator structures with structural support elements. The oscillators are positioned and connected to the base board in such a way that they serve dual purposes: receiving signals in specific frequency bands and providing structural reinforcement to the base board, thereby simultaneously improving signal reception quality and enhancing base board strength without requiring separate support structures.
3Device complexity
If the antenna is designed to receive single frequency band, then the structure remains simple, but it cannot receive multiple frequencies in the same band simultaneously
Solution Approach 1:
The antenna oscillator is designed with multi-functionality to receive both UHF and VHF frequency bands simultaneously. Multiple oscillator elements are integrated into a single antenna structure, each tuned to different frequency bands. This universal design allows the antenna to function across multiple frequency ranges without requiring separate antenna systems, thereby enhancing adaptability while maintaining reasonable structural simplicity through shared support infrastructure.

AI summary
A flattened antenna oscillator structure has a square frame with an opening in the middle of a lower side. Two vertical oscillator leads parallel to left and right sides are symmetrically arranged inside the frame. Lower ends of the vertical oscillator leads extend into the opening to form feeder contacts. The left and right sides of the frame have plural inward extending matching leads connected with the vertical oscillator leads. The pair of leads at the uppermost end is connected with the upper ends of the vertical oscillator leads. The layout of the antenna oscillator improves the anti-deformation ability of a whole antenna while combining different frequency bands and different frequencies, which improves the signal reception and receiving quality of the antenna oscillator. A variety of modulation structures are further arranged to maximize the receiving power of the antenna and reduce the loss caused by mutual interference between signals.
