Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Millimeter wave (mmW) antennas in wireless devices face transmission loss due to distance from the mmW antenna circuit module to the antenna arrays, exacerbated by hand-blocking and atmospheric attenuation, leading to inefficiencies in signal transmission.
Innovation Solution
A wireless electronic device design that integrates a mmW antenna array directly on the surface of a cellular antenna with an mmW circuit, utilizing a grounding element with a power trace and control line on a flexible film to reduce signal loss, forming an antenna loop with the cellular antenna and ground plane.

Engineering Contradiction Analysis
1Quantity of substance
If mmW antennas are added to a cellular mobile terminal, then bandwidth for transmission is increased, but internal transmission loss increases due to distance from the mmW antenna circuit module to the mmW antenna arrays
Solution Approach 1:
The patent combines the mmW antenna array and mmW circuit module into a single integrated module, placing them in close proximity to each other. This merging eliminates the need for separate circuit modules and long transmission paths, thereby reducing internal transmission loss while maintaining the increased bandwidth capability of mmW antennas
Solution Approach 2:
The mmW antenna array is integrated within the cellular antenna structure, with the mmW circuit module nested alongside the antenna elements. This nested configuration allows the mmW components to be housed within the existing antenna footprint, minimizing distance and reducing signal loss
2Reliability
If mmW antennas are placed at a distance from the circuit module for proper signal processing, then signal processing capability is maintained, but transmission loss from hand-blocking and atmospheric attenuation is exacerbated
Solution Approach 1:
By merging the mmW antenna array and circuit module into a single integrated unit, the patent minimizes the distance between components. This reduces the exposure of signals to harmful external factors such as hand-blocking and atmospheric attenuation, while the integrated circuit module maintains full signal processing capability
3Loss of energy
If the distance between the mmW circuit module and antenna array is reduced to minimize transmission loss, then internal transmission loss is reduced, but the complexity of integrating the circuit directly on the antenna surface increases
Solution Approach 1:
The patent merges the mmW circuit module and antenna array into a single integrated module, simplifying the overall device architecture. This integration reduces the number of separate components and interconnections needed, thereby reducing integration complexity while minimizing transmission loss through close proximity placement
