Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional single-branch antenna structure is used, then the structure is simple, but the bandwidth and resonance frequency coverage are insufficient
Solution Approach 1:
The antenna is divided into multiple independent branches (first branch, second branch, third branch, and parasitic branch), each capable of resonating at different frequencies. This segmentation allows the antenna to cover multiple frequency bands simultaneously while maintaining a relatively simple overall structure based on the base frame.
Solution Approach 2:
The antenna structure is designed to perform multiple functions: the first branch handles frequencies above 24 GHz, the second branch handles frequencies below 6 GHz, and the parasitic branch provides additional resonance. This multi-functionality enables a single antenna to meet diverse 5G communication requirements across different frequency bands.
2Adaptability or versatility
If multiple branches are added to increase bandwidth, then the frequency coverage is improved, but the assembly difficulty and impedance matching complexity increase
Solution Approach 1:
Multiple branches are integrated onto a single base frame structure, sharing common mounting points and spatial arrangement. The first, second, and parasitic branches are positioned to utilize the available space efficiently, reducing the number of separate components and simplifying the assembly process despite the increased functional complexity.
3Adaptability or versatility
If the antenna structure is expanded to cover more frequency bands, then the communication performance is improved, but the space occupation increases
Solution Approach 1:
The antenna design transitions from a planar two-dimensional layout to a three-dimensional structure by utilizing vertical spacing and spatial arrangement of branches. The parasitic branch is positioned in the layout region to form a second slot with the second branch, creating additional resonance paths without significantly increasing the footprint area, thus achieving dual-frequency 5G communication capability within limited space.

AI summary
Disclosed in the embodiments of the present disclosure are an antenna assembly and a communication terminal, where a layout region is arranged at an edge position on a base frame, and a radiation pattern and a parasitic branch are arranged together on the layout region. Thus, in an aspect, when the communication terminal is assembled, it is convenient to observe the connection between a feed point and a ground point of the antenna assembly, thereby improving the assembly efficiency of the communication terminal. In another aspect, a parasitic branch is arranged near a second branch, so that the antenna has a larger bandwidth in a high frequency band. In yet another aspect, configuring a shape of a first slot, a second slot, and the parasitic branch enables direct adjustment to a resonance frequency of the antenna, which improves the adaptability of the antenna to different applications.
