Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna module is made large in size, then broadband and multi-band capabilities are improved, but the overall volume of the wireless transceiver becomes too large
Solution Approach 1:
Multiple antennas are integrated into a single compact module with a shared center base and extension legs, combining several antenna elements into one unified structure that provides broadband and multi-band capabilities while maintaining a small overall volume
Solution Approach 2:
The antenna module employs a nested structure where extension legs extend from the center base, and antennas are positioned along these legs, creating a compact nested arrangement that maximizes functionality within minimal space
2Volume of stationary object
If the antenna module volume is limited to be small in size, then the wireless transceiver becomes lightweight and compact, but the operation band of the antenna module is limited
Solution Approach 1:
Different portions of the antenna module are designed with different characteristics - the center base provides a stable reference point, extension legs provide structural support and electrical connection, and radiation elements at various positions handle different frequency bands, allowing each local region to optimize for its specific function
Solution Approach 2:
The antenna module utilizes three-dimensional space efficiently by extending elements in multiple directions from the center base, employing vertical and horizontal dimensions to accommodate multiple antenna elements and achieve broadband operation within a compact footprint
3Volume of stationary object
If the antenna module is made compact, then the wireless transceiver meets size demands, but poor stability of radiation pattern is generated
Solution Approach 1:
The antenna module employs asymmetric positioning of antenna elements relative to the center base, with extension legs extending in specific directions and antennas positioned at optimized locations, creating an asymmetric structure that maintains stable radiation characteristics while achieving compact dimensions
Solution Approach 2:
The center base serves multiple functions simultaneously - it provides structural support, electrical grounding, and a reference point for all extension legs, while the extension legs themselves serve both mechanical support and electrical transmission functions, reducing the need for additional components and improving overall stability

AI summary
An antenna module includes a center base and several antennas disposed around the center base. The center base has several extension legs extending from the center base, and each antenna extends from an end of the corresponding extension leg opposite to the center base, so as to form the antenna module symmetrically arranged around the center base. The type of the antenna may be a single-frequency antenna and a dual-frequency antenna. The antenna module is an integral structure formed by directly bending a single metal plate, thus greatly reducing the volume and the manufacturing cost of the antenna module. Moreover, with the design of the center base and a symmetrical antenna group, the antenna module is capable of receiving and transmitting signals with two or more frequency bands, thus greatly increasing the application range of the antenna module.
