Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antennas often create dead zones in their radiation patterns, making it difficult to provide consistent wireless communication coverage beyond the proximity of a building, especially in areas like store parking lots.
Innovation Solution
The antenna system includes radiating elements and reflectors, with a conical and planar reflector configuration that extends the coverage area by reflecting radiation downward and outward, eliminating null zones and enhancing signal strength beyond the building's exterior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional antennas are mounted on building exteriors, then wireless coverage is provided near the building, but dead zones are created that prevent coverage beyond the building proximity
Solution Approach 1:
The antenna system segments the radiation pattern into multiple directional components using quadrantal loop antennas arranged at 90-degree intervals. Each antenna element radiates in specific directions, and their combined patterns create overlapping coverage zones that eliminate dead spots, allowing comprehensive coverage beyond the building exterior.
Solution Approach 2:
The invention introduces a vertical dimension to the radiation pattern by using elevated mounting positions and creating three-dimensional coverage zones. The loop antennas are positioned and oriented to radiate both horizontally and vertically, extending coverage in multiple spatial dimensions rather than confined to a single plane near the building.
2Length of moving object
If antenna height is increased to extend coverage beyond building proximity, then coverage distance improves, but dead zones and signal degradation occur in intermediate areas
Solution Approach 1:
The antenna system applies local quality by optimizing the radiation characteristics of each quadrantal loop antenna element for specific directional requirements. Each antenna is oriented to provide enhanced signal strength in particular zones, creating locally optimized coverage patterns that collectively eliminate dead zones while extending overall coverage distance.
3Reliability
If multiple antennas are deployed to eliminate dead zones, then coverage consistency improves, but system complexity increases
Solution Approach 1:
The invention merges multiple loop antenna elements into a single integrated antenna assembly mounted at one location. The quadrantal loop antennas are electrically and physically combined in a coordinated arrangement, providing multi-directional coverage from a unified structure rather than requiring separate antenna installations at multiple locations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a robust wireless communication signal that extends further than conventional systems, ensuring coverage both near and along the periphery of the building, such as in a parking lot, with improved signal strength and coverage distance.
Implementation Method 1
The reflectors can be disposed with respect to the radiating elements to reflect radiation from the radiating elements to generate a coverage area that exceeds the coverage area generated by the radiating elements without the reflectors
Implementation Method 2
a first reflector centrally located with respect to the radiation elements in a radiation direction of the radiation elements away from the plane
