Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a monopole antenna and circularly polarized antenna are integrated into a single antenna assembly, then communication across multiple frequency bands (5G, GPS, Wifi) is enabled, but the device complexity increases due to the need to integrate different antenna types and their supporting components
Solution Approach 1:
The patent combines a monopole antenna and a circularly polarized antenna into a single integrated antenna assembly. The monopole antenna is positioned within the cavity of the column substrate, while the circularly polarized antenna with its four isolated magnetic dipole elements is mounted on the exterior surfaces. This merging allows the antenna assembly to simultaneously support multiple frequency bands (5G: 5000-5900 MHz, GPS: 1560-1620 MHz, Wifi: 2400-2500 MHz) without requiring separate antenna units, thereby reducing overall system complexity while maintaining multi-frequency capability.
Solution Approach 2:
The antenna assembly is designed to perform multiple functions across different frequency bands using a single integrated structure. The monopole antenna handles 5G communications, while the circularly polarized antenna with its isolated magnetic dipole elements handles GPS and Wifi communications. The column substrate serves as both the structural support and the mounting platform for both antenna types, creating a universal antenna solution that replaces what would traditionally require multiple separate antenna systems.
2Adaptability or versatility
If additional components are added to integrate monopole and circularly polarized antennas effectively, then communication performance across frequency bands improves, but the footprint of the antenna assembly increases
Solution Approach 1:
The monopole antenna is nested within the cavity of the column substrate, utilizing the internal space rather than requiring additional external area. The circularly polarized antenna's isolated magnetic dipole elements are positioned on the exterior surfaces of the column substrate, effectively using the available surface area without requiring a larger overall footprint. This nested arrangement allows both antenna types to coexist in a compact configuration.
Solution Approach 2:
The antenna assembly utilizes three-dimensional space efficiently by placing the monopole antenna within the internal cavity (using depth/volume) and the circularly polarized antenna elements on the external surfaces (using surface area). This multi-dimensional arrangement allows the integration of multiple antenna types without simply expanding the two-dimensional footprint, thereby maintaining a compact overall size while achieving comprehensive frequency band coverage.

Function Achieved in This Case
The solution enables efficient communication across multiple frequency bands, including 5G, GPS, and Wifi, while maintaining a compact footprint by integrating the monopole antenna within the column substrate, facilitating seamless network communication without the need for extra components.
Implementation Method 1
Each of the plurality of isolated magnetic dipole elements can be coupled to a radio frequency (RF) phase shifter circuit. In this manner, a RF signal the RF phase shifter circuit provides to one isolated magnetic dipole element of the circularly polarized antenna can be out-of-phase relative to a RF signal provided to every other isolated magnetic dipole element of the circularly polarized antenna.
