Multi-band Dual-polarized Antenna Structure Layout Area Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-band antenna structures occupy large areas due to the layout of multiple antenna arrays, making them bulky and inefficient in terms of size and space utilization.
Innovation Solution
A multi-band dual-polarized antenna structure is designed with a first antenna array in one row operating at a first frequency and a second antenna array in the same row operating at a second frequency with a different polarized direction, sharing common antenna elements to reduce the overall layout area, allowing for simultaneous operation at multiple frequencies.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antenna arrays are used to support multi-band operation, then multiple data transmission capabilities at different frequencies are achieved, but the layout area occupied by the antenna arrays increases
Solution Approach 1:
The patent combines multiple antenna arrays (first, second, and third antenna arrays operating at different frequencies) into a single integrated antenna structure. The antenna elements are shared across multiple frequency bands, with the first antenna array operating at a first frequency, the second antenna array at a second frequency with a first polarized direction, and the third antenna array at the second frequency with a second polarized direction. This merging approach allows multi-band dual-polarized operation while significantly reducing the overall layout area compared to using separate antenna arrays for each frequency band.
Solution Approach 2:
The antenna structure is designed to perform multiple functions simultaneously: it supports operation at multiple frequency bands (first frequency, second frequency) and multiple polarized directions (first polarized direction, second polarized direction). The same physical antenna elements serve multiple purposes across different frequency bands and polarization modes, making the antenna structure universal and eliminating the need for separate dedicated arrays for each function.
2Adaptability or versatility
If multiple antenna arrays are deployed to achieve dual-polarized multi-band operation, then comprehensive communication coverage is provided, but the product size increases
Solution Approach 1:
The patent merges multiple antenna arrays that would traditionally be required for dual-polarized multi-band operation into a single compact antenna structure. By integrating the first antenna array (first frequency), second antenna array (second frequency, first polarization), and third antenna array (second frequency, second polarization) into one unified structure with shared elements, the overall volume and footprint of the product are significantly reduced while maintaining full dual-polarized multi-band capability.
Solution Approach 2:
The antenna structure employs a nested arrangement where antenna elements for different frequency bands and polarization directions are embedded within the same physical space. The first, second, and third antenna arrays are nested together, with their elements interwoven or positioned in close proximity, allowing multiple functional layers to coexist in a compact volume, thereby reducing product size while achieving comprehensive communication coverage.
