Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna radiation patterns in electronic devices are often constrained, leading to wasted energy and degraded communication performance due to their fixed orientations, which are not well-suited for various deployment geometries and environments.
Innovation Solution
The integration of a static lens within the antenna cover, which can be selected based on deployment geometry, dynamically adjusts the antenna radiation pattern to converge, diverge, or change angular elevation, providing phase corrections and optimizing energy use across different environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed antenna radiation pattern is used, then the device structure is simple, but the communication performance is degraded due to wasted energy in unnecessary directions
Solution Approach 1:
The patent applies dynamics by making the antenna radiation pattern adjustable rather than fixed. The antenna cover can be reconfigured to change the radiation pattern characteristics, allowing the system to adapt to different deployment geometries and environmental conditions, thereby directing energy only where needed and reducing waste.
Solution Approach 2:
The patent changes the radiation pattern parameters (directionality, gain distribution) by using reconfigurable antenna elements that can be selectively activated or deactivated. This allows dynamic adjustment of the radiation pattern to match the deployment scenario, optimizing energy utilization while maintaining structural simplicity.
2Reliability
If the antenna radiation pattern is adjusted to suit specific deployment geometries, then the communication performance is improved, but the device complexity increases
Solution Approach 1:
The patent uses dynamic reconfiguration of antenna elements to adapt the radiation pattern to different deployment scenarios. By selectively activating or deactivating antenna elements, the system can optimize communication performance for various geometries without requiring multiple physical antenna arrays, thus managing complexity while improving reliability.
Solution Approach 2:
The patent implements a universal antenna cover design that can serve multiple deployment scenarios through reconfiguration. The same physical antenna structure can be adapted to different geometries and environments by changing which elements are active, providing multi-functionality without increasing hardware complexity.
3Ease of manufacture
If monopole or dipole antenna patterns are used, then the antenna design is simple, but the energy distribution is uneven across different angles causing degraded performance
Solution Approach 1:
The patent applies local quality by creating non-uniform energy distribution in the radiation pattern, concentrating power in specific directions where it is needed rather than distributing it evenly in all directions. This is achieved by selectively activating antenna elements to create directional beams, improving communication efficiency while maintaining design simplicity.
Solution Approach 2:
The patent changes the radiation pattern parameters from the standard monopole/dipole patterns to customized patterns suited for specific deployment geometries. By adjusting which antenna elements are active and their respective weights, the system can optimize energy distribution to match the required coverage areas, improving productivity without complex redesign.

an antenna cover that includes an integrated static lens, where the antenna cover is selected from a set of antenna covers that includes different integrated static lenses.

Data Source
AI summary
An electronic device that communicates a packet or a frame is described. This electronic device includes: at least an antenna having an antenna radiation pattern; an interface circuit; and an antenna cover that includes an integrated static lens, where the antenna cover is selected from a set of antenna covers that includes different integrated static lenses. During operation, the interface circuit may transmit, from the antenna, wireless signals corresponding to the packet or the frame, where the integrated static lens modifies the antenna radiation pattern of the antenna. For example, the integrated static lens may cause the wireless signals to converge or diverge. Alternatively, the integrated static lens may change an angular elevation of the antenna radiation pattern and/or may provide a correction for pathloss as a function of angle. Note that the integrated static lens may be a stepwise approximation to a predefined function.
