Dual-Grip Drone Jammer Directional Antenna Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable drone jammers are ineffective in specifically targeting drones due to their omnidirectional nature, lack of ruggedness, and inability to differentiate between drone signals and non-offensive devices, leading to unintended interference with civilian devices and strain on operators during use.
Innovation Solution
A dual-grip portable countermeasure device with a directional antenna and signal disruption components, designed in a rifle-like form factor, allowing for targeted jamming of drone control and GPS signals while minimizing impact on other devices, featuring a self-contained power supply and ergonomic design to reduce operator strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If omnidirectional portable jammers are used, then the jamming radius is extended, but non-offensive devices are also interfered with
Solution Approach 1:
The patent applies directional antenna technology to create localized jamming zones, allowing the jamming signal to be concentrated in specific directions rather than radiating omnidirectionally. This enables the jammer to affect only the targeted drone while leaving other devices in different directions unaffected, thus extending effective jamming range without causing widespread interference.
Solution Approach 2:
The jamming system is segmented into multiple directional antenna elements that can be independently controlled. This segmentation allows the system to create multiple independent jamming zones or to precisely control the spatial distribution of jamming energy, enabling selective interference with specific drones while preserving operation of non-offensive devices.
2Adaptability or versatility
If multiple antennae are used for different frequency bands, then the jamming capability is improved, but the device becomes more fragile and less rugged
Solution Approach 1:
The patent combines multiple frequency band capabilities into a single integrated directional antenna system. Rather than using separate physical antennae for different frequency bands, the design merges these functions into one ruggedized directional antenna structure that can handle multiple frequency bands, thereby maintaining jamming versatility while improving device reliability and ruggedness.
Solution Approach 2:
The directional antenna system is designed with universal multi-functionality to operate across multiple frequency bands used by various drone types. This single antenna structure replaces multiple specialized antennae, providing broad-spectrum jamming capability while reducing the number of fragile components and improving overall device ruggedness for field operations.
3Stability of the object's composition
If conventional two-hand rifle grip is used, then the weapon stability is improved, but operator arm strain increases during sustained aiming
Solution Approach 1:
The patent incorporates a counterweight mechanism in the rear grip area that balances the weight distribution of the directional jammer. This counterweight design reduces the torque and strain on the operator's extended arm during sustained aiming, allowing the operator to maintain stable two-hand grip without excessive fatigue, thereby improving ease of operation while preserving weapon stability.

AI summary
A portable countermeasure device is provided comprising one or more directional antennae, one or more disruption components and at least one activator. The portable countermeasure device further comprises a body having a dual-grip configuration, with the directional antennae are affixed to a front portion of the body. The one or more disruption components may be internally mounted within the device body. The dual-grip configuration allows an operator to use his body to steady and support the device while maintaining the antenna on target. The second grip is positioned adjacent the first grip, with the first grip angled toward the rear of the device and the second grip angled toward the front of the device. The portable countermeasure device is aimed at a specific drone, the activator is engaged, and disruptive signals are directed toward the drone, disrupting the control, navigation, and other signals to and from the drone.
