Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antennas face challenges in achieving full coverage on a horizontal plane while maintaining a high gain, as directional antennas provide high gain in specific directions but not full coverage, and omnidirectional antennas offer full coverage but with low gain.
Innovation Solution
The antenna system incorporates a feeding part and at least two oscillators with variable inductance circuits, allowing any oscillator to function as an excitation, excited, reflector, or director, enabling multiple statuses and adaptive signal emission to ensure high quality and coverage through adjustable inductance values and switchable circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a directional antenna is used, then the gain in a specific direction is improved, but the coverage on a horizontal plane deteriorates
Solution Approach 1:
The patent employs dynamic switching between different antenna modes by controlling the inductance values of circuits connected to different oscillators. The system can dynamically transition between omnidirectional and directional radiation patterns, and between different directional orientations, allowing the antenna to adapt its beam direction and coverage pattern in real-time to meet varying communication requirements
Solution Approach 2:
The antenna system integrates multiple oscillators (at least two) with switchable circuit connections, enabling a single antenna structure to perform multiple functions: omnidirectional communication, unidirectional high-gain communication, and bidirectional communication. This multi-functional design resolves the contradiction by allowing the antenna to be universally applicable to different scenario requirements
2Adaptability or versatility
If an omnidirectional antenna is used, then the coverage on a horizontal plane is improved, but the gain deteriorates
Solution Approach 1:
The system dynamically adjusts its radiation pattern by switching circuit configurations. When high gain is needed, the system transitions to a directional mode with selected oscillators connected through inductance circuits. When full coverage is prioritized, it switches to omnidirectional mode, thereby dynamically optimizing the trade-off between gain and coverage based on real-time requirements
Solution Approach 2:
The patent changes the electrical parameters of the antenna system by adjusting inductance values in the circuits connected to different oscillators. By varying these inductance parameters, the system transforms the radiation characteristics from omnidirectional to directional patterns, effectively changing the gain and coverage parameters to match different operational scenarios

AI summary
An antenna, an antenna control method, an antenna control apparatus, and an antenna system, where the antenna includes a feeding part and at least two oscillators, and a circuit with a variable inductance value is disposed between any oscillator and the feeding part. When the inductance value of the circuit between the oscillator and the feeding part is zero the oscillator is used as an excitation oscillator. When the inductance value is greater than zero, the oscillator is used as an excited oscillator. Any oscillator may be used as an excitation oscillator or an excited oscillator. The antenna can implement full coverage on a horizontal plane and has a relatively high gain.
