Configurable Stacked Antenna Array for Wireless Access Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless access points have limitations in flexibility, range of coverage, and ease of maintenance due to their fixed configuration with omnidirectional antennas operating at a singular radio band, requiring complete replacement for upgrades or additions, which leads to channel congestion and decreased network performance as more devices connect.
Innovation Solution
A configurable wireless access point with a stacked antenna array, where each layer operates on a different wireless radio band, allowing for sectorization and independent accessibility of antenna elements, enabling modular design with interchangeable components and reduced interference through shielding, facilitating easy upgrades and expansions without replacing the entire system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wireless access points use fixed configuration with omnidirectional antennas operating at a singular radio band, then device simplicity is maintained, but flexibility and adaptability are reduced
Solution Approach 1:
The patent divides the antenna system into multiple independent layers, each operating at different radio bands (2.4 GHz and 5 GHz). Each layer can be independently configured, upgraded, or replaced without affecting other layers, thereby increasing flexibility while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The patent transitions from a single-layer antenna configuration to a multi-layer stacked architecture, adding vertical dimensionality to the system. This allows simultaneous operation of multiple radio bands and antenna types (omnidirectional and directional) without increasing horizontal space requirements, enhancing adaptability while preserving compact form factor.
2Adaptability or versatility
If conventional wireless access points use fixed configuration, then manufacturing and deployment are simplified, but range of coverage and network capacity are limited
Solution Approach 1:
The stacked antenna array design enables a single access point to perform multiple functions simultaneously: supporting both 2.4 GHz and 5 GHz bands, providing omnidirectional and directional coverage patterns, and serving different sector requirements. This multi-functionality expands range of coverage while maintaining straightforward deployment through standardized mounting structures.
3Ease of repair
If conventional wireless access points require complete replacement for upgrades, then system reliability is maintained, but maintenance burden and loss of time increase
Solution Approach 1:
The patent implements modular antenna layers that can be independently accessed and replaced. When an antenna or layer needs upgrading or repair, only that specific component is removed and replaced, not the entire access point system. This segmentation dramatically reduces maintenance time and effort while preserving system reliability through hot-swappable components.
4Adaptability or versatility
If more devices connect to the same channel, then network connectivity is improved, but channel congestion and signal interference increase
Solution Approach 1:
The patent divides the wireless network into multiple sectors using directional antennas, each operating on designated channels. This sectorization segments the network traffic, allowing more devices to connect simultaneously across different sectors and channels without causing congestion or interference in any single sector, thereby increasing overall network capacity while minimizing harmful interference.

AI summary
A configurable wireless communications module may include a first antenna layer having one or more antenna operating at a first wireless radio band; a second antenna layer having one or more antenna operating at a second wireless radio band; and a support structure for supporting the first antenna layer and the second antenna layer in a stacked configuration. The first antenna layer and/or the second antenna layer may be divided into sectors, with a directional antenna assigned to each sector, and with each directional antenna operating on a designated channel. Antenna layers may be individually accessed and removed/inserted for ease of maintenance and enhancement of function. An optional accessory module may support additional sensors and elements beyond antennas to allow for enhanced customization based on the intended application.
