Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electromagnetic wave transmitters, particularly those operating at millimeter- and terahertz frequencies, face challenges due to significant space requirements, energy loss, and frequency instability caused by foreign objects or electrostatic signals, leading to inefficiencies and additional circuit complexities.
Innovation Solution

Engineering Contradiction Analysis
1Volume of moving object
If traditional antenna-oscillator coupling is used, then electromagnetic wave transmission is achieved, but significant space is required for the radiator structure, oscillator circuitry, and connecting structure
Solution Approach 1:
The patent combines the antenna, resonator, and diplexer into a single integrated RDA structure. The outer band and core structure form a unified resonating system that eliminates the need for separate oscillator circuitry and connecting structures, thereby reducing space requirements while maintaining transmission functionality
Solution Approach 2:
The RDA structure performs multiple functions simultaneously: it acts as an antenna for electromagnetic radiation, a resonator for frequency selection, and a diplexer for signal separation. This multi-functionality eliminates the need for separate dedicated components for each function, reducing overall device complexity and space
2Loss of energy
If traditional antenna-oscillator connection is used, then electromagnetic wave transmission is achieved, but losses of electromagnetic wave energy occur which are more significant at higher frequencies
Solution Approach 1:
The resonator acts as an intermediary between the input signal and the antenna output. By introducing this intermediate resonating structure, the system achieves frequency-selective energy transfer that minimizes losses, particularly at millimeter- and terahertz frequencies where traditional direct coupling suffers from significant energy loss
Solution Approach 2:
The patent employs resonant vibration at specific frequencies to enhance energy transfer efficiency. The outer band and core structure are designed to resonate at predetermined frequencies, creating constructive interference that maximizes electromagnetic wave transmission while minimizing energy loss through the Q-factor of the resonating system
3Reliability
If direct coupling of antenna to oscillator is used, then transmission is achieved, but a large pulling effect occurs causing frequency and power changes due to foreign objects or electrostatic signals
Solution Approach 1:
The patent changes the coupling parameters by introducing a resonant structure with specific geometric parameters (outer band dimensions, core structure configuration, gap distances). These parameter changes create a high-Q resonating system that is inherently less sensitive to external perturbations, thereby reducing the pulling effect and improving frequency stability without requiring additional circuit blocks
Solution Approach 2:
The RDA structure incorporates localized regions with different electromagnetic properties - the outer band for radiation, the core structure for resonance, and the gaps for coupling control. This local differentiation of functional qualities allows each region to optimize its specific role while collectively providing frequency stability against external influences
