Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microwave weapons lack flexibility in emitting waves with multiple polarizations and directions, requiring multiple antennas and complex integration for target tracking, which complicates system implementation and processing of information from separate reception channels.
Innovation Solution
A method and antenna design that uses out-of-phase elementary antennas to emit coherent waves in multiple directions with opposite polarizations, allowing for simultaneous transmission in two distinct directions with the same frequency spectrum and phase, minimizing interference and enabling flexible orientation of coherent waves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate antennas are used to emit waves with different polarizations and directions, then the microwave weapon can transmit in multiple directions with different polarizations, but the system complexity and integration difficulty increase
Solution Approach 1:
The patent combines multiple antenna functions into a single array antenna structure. The antenna array includes multiple antenna elements that can be independently controlled to emit electromagnetic waves with different polarizations and transmission directions simultaneously, eliminating the need for multiple separate antennas and their associated integration complexity
Solution Approach 2:
The array antenna is designed to perform multiple functions simultaneously - it can transmit electromagnetic waves with different polarizations (horizontal, vertical, circular) and in different directions using the same physical structure, making the antenna system universal and multi-functional
2Power
If a single antenna is used to emit high-power electromagnetic waves, then the power output is sufficient, but the antenna can only transmit in a single direction with a single polarization
Solution Approach 1:
The antenna is divided into multiple independent antenna elements arranged in an array configuration. Each element can be independently controlled to emit electromagnetic waves with specific polarization and direction, allowing the overall system to achieve high power output while maintaining versatility in transmission capabilities
Solution Approach 2:
The antenna elements are equipped with independent phase shifters and amplitude controllers that allow dynamic adjustment of the radiation pattern, polarization, and transmission direction in real-time, enabling the single antenna structure to adapt to different transmission requirements

AI summary
The method involves determining a set of amplitude values (340) of a set of components, and providing a signal that is electronically processed. A value of an angle of a plane is calculated (350) from the amplitude values of each of the set of components. A set of electromagnetic waves emitted by the antenna network is phase shifted at an angle of 90 degrees with regard to each other. A set of elementary antennas or radial line antenna is provided in an antenna network, where the antennas are able to be rotated mechanically. An independent claim is also included for an antenna network.
