Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soldiers face challenges with cumbersome and time-consuming transitions between linearly polarized and circularly polarized antennas for line-of-sight (LOS) and satellite communication (SATCOM) due to the need for separate antennas, which are cumbersome and not suitable for rapid deployment on the move.
Innovation Solution
A dual-polarized antenna system that can be quickly transformed between linearly and circularly polarized configurations using a support structure with spring-loaded elements, allowing for omnidirectional radiation patterns suitable for both LOS and SATCOM, and is compact and lightweight for easy carrying and deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate linearly polarized and circularly polarized antennas are used for LOS and SATCOM communications, then communication reliability is improved, but device complexity and ease of operation deteriorate due to the need to carry and switch between multiple antennas
Solution Approach 1:
The patent combines both linearly polarized and circularly polarized antenna capabilities into a single integrated antenna structure. The antenna elements can be configured to provide linear polarization for LOS communications or circular polarization for SATCOM communications, eliminating the need to carry and switch between separate antennas while maintaining communication reliability for both modes
Solution Approach 2:
The antenna is designed with multi-functionality to perform both LOS and SATCOM communications. By incorporating adjustable polarization capabilities and reconfigurable antenna elements, a single antenna structure can adapt to different communication modes (linear polarization for LOS, circular polarization for SATCOM), providing universal communication capability without requiring multiple specialized antennas
2Reliability
If separate linearly polarized and circularly polarized antennas are used for LOS and SATCOM communications, then communication reliability is improved, but ease of operation worsens due to time-consuming transitions between antenna configurations
Solution Approach 1:
The antenna incorporates dynamic reconfigurability allowing real-time switching between linear and circular polarization modes. The antenna elements can be electrically or mechanically adjusted during operation to change polarization characteristics, enabling rapid transitions between LOS and SATCOM modes without the time-consuming process of physically replacing antenna components
3Adaptability or versatility
If multiple separate antennas are carried for different communication modes, then communication versatility is improved, but weight and ease of operation worsen due to the burden of carrying and managing multiple antennas
Solution Approach 1:
The patent merges the functionality of multiple separate antennas (linearly polarized for LOS and circularly polarized for SATCOM) into a single integrated antenna structure. This consolidation maintains full communication versatility for both LOS and SATCOM modes while significantly reducing the total weight and number of components that soldiers must carry and manage
4Adaptability or versatility
If multiple separate antennas are carried for different communication modes, then communication versatility is improved, but device complexity worsens due to the need to manage and switch between multiple antenna systems
Solution Approach 1:
The antenna is designed as a universal multi-functional system that can operate in both LOS and SATCOM modes with a single device. The integrated design includes unified control mechanisms and standardized interfaces, eliminating the complexity of managing multiple separate antenna systems while maintaining full communication versatility across different operational modes

AI summary
Embodiments of a wide band multi-polarization antenna system are described, which can be attached to the back or front of a soldier's vest or backpack. The antenna system can allow for release of pre-shaped integral radiating elements that spring into a geometric configuration suitable for circular polarization radiation or linear polarization over a desired band of frequencies. The antenna system can provide, when collapsed, linear polarized line-of sight capability over a wide band of frequencies. In a collapsed low-profile state, the antenna system can remain on the soldier, but out of the way for maneuvering.
