Antenna System With Segmented Receiver Transmitter Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing MIMO antenna systems face challenges with increased size, weight, cost, and yield rate due to the number of antennas, and insufficient isolation between receivers and transmitters, leading to intermodulation issues and decreased radio frequency performance.
Innovation Solution
The antenna system is designed with a passive or active architecture that isolates receiver and transmitter components using separate antenna unit sets, where each antenna unit is connected only to either a receiver or a transmitter, enhancing isolation and improving intermodulation performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the quantity of antenna units is increased to satisfy MIMO requirements, then system capacity is improved, but consumable, size, weight, costs, and yield rate greatly increase
Solution Approach 1:
The antenna array is divided into a first antenna unit set connected to receivers and a second antenna unit set connected to transmitters. This segmentation allows independent optimization of each unit type, reducing the complexity of individual antenna units while maintaining the overall MIMO system capacity through the combined array of multiple units.
2Productivity
If the quantity of antenna units is increased to satisfy MIMO requirements, then system capacity is improved, but yield rate decreases
Solution Approach 1:
By segmenting the antenna array into standardized first antenna units (for receivers) and second antenna units (for transmitters), each unit can be manufactured independently using standardized processes. This improves yield rate by allowing defective units to be replaced without affecting the entire system, while still achieving the required system capacity through the combined array.
Solution Approach 2:
The first antenna units and second antenna units can be designed as universal modules that can be applied across different MIMO system configurations. This universality simplifies manufacturing processes and improves yield rate through standardized production, while the flexible combination of these universal units enables achievement of various system capacity requirements.
3Productivity
If existing antenna array configuration is used, then multi-column antenna requirement is met, but isolation between receiver and transmitter is insufficient causing intermodulation
Solution Approach 1:
The antenna array is segmented into a first antenna unit set exclusively connected to receivers and a second antenna unit set exclusively connected to transmitters. This physical and functional segmentation creates inherent isolation between receiver and transmitter paths, preventing intermodulation interference while maintaining the multi-column antenna configuration needed for MIMO system capacity.

AI summary
Embodiments of the present invention disclose an antenna system, including a receiver set, a transmitter set, and an antenna array, where the receiver set includes a plurality of receivers, and the transmitter set includes a plurality of transmitters; the antenna array includes a first antenna unit set and a second antenna unit set; the first antenna unit set includes at least one first target antenna unit, and the second antenna unit set includes at least one second target antenna unit; and any one of the at least one first target antenna unit is connected to any receiver in the receiver set, and any one of the at least one second target antenna unit is connected to any transmitter in the transmitter set. In this way, the receiver and the transmitter are completely isolated from each other, thereby increasing isolation between the receiver and the transmitter, and effectively improving an intermodulation indicator of the antenna system.
