Problem
Conventional triple-band antenna arrays for cellular base stations are bulky and visually impactful, leading to increased costs and difficulties in acquiring new sites due to their large size and number, which complicates the deployment and maintenance of mobile telecommunication networks.
Innovation Solution
A slim triple-band antenna array is developed, integrating multiple mobile/cellular services into a compact radiating system using interlaced arrangements of small radiating elements, allowing for reduced size and weight, and incorporating an adjustable electrical tilt mechanism for optimized coverage and capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional triple-band antenna arrays are used to provide multi-service coverage, then network capacity and service integration are improved, but the size and visual impact of base stations increase
Solution Approach 1:
The patent combines multiple antenna arrays for different frequency bands (GSM, DCS, PCS, UMTS) into a single integrated antenna structure. This merging of previously separate antenna systems into one unified array reduces the overall space occupied while maintaining the ability to provide multi-service coverage across multiple frequency bands.
Solution Approach 2:
The integrated antenna array is designed to perform multiple functions simultaneously, supporting multiple frequency bands and service types (2G, 3G, 4G) within a single structure. This multi-functional design eliminates the need for separate dedicated antennas for each service, thereby reducing base station footprint while maintaining versatility.
2Adaptability or versatility
If multiple independent antenna arrays are deployed for different frequency bands, then service coverage is improved, but the number of base station sites required increases
Solution Approach 1:
The patent merges multiple frequency band operations into a single integrated antenna array that can simultaneously handle GSM, DCS, PCS, and UMTS bands. This consolidation allows one base station site to provide coverage that previously required multiple separate sites, thereby reducing the total quantity of base station locations needed.
Solution Approach 2:
The antenna array is designed with universal capability to support multiple generations of mobile services (2G, 3G, 4G) and multiple frequency bands within a single structure, enabling one site to fulfill the role of multiple specialized sites and reducing the overall number of base stations required in the network.
3Reliability
If conventional antenna arrays are used, then reliable communication coverage is achieved, but deployment and maintenance complexity increases
Solution Approach 1:
The patent combines multiple antenna systems into a single integrated array, reducing the number of separate components that need to be deployed and maintained. This consolidation simplifies the deployment process and reduces maintenance complexity while maintaining reliable communication coverage across multiple frequency bands through the unified structure.
