Solution Overview
Problem
Conventional E-band antennas face signal attenuation over long distances and in adverse weather conditions, requiring additional antennas for redundancy, which increases costs and complexity.
Innovation Solution
A telecommunications device with a dual-band feed design that operates simultaneously in the E-band (71-86 GHz) and lower frequency ranges (17-40 GHz), featuring a parabolic mirror reflector, corrugated feed, and a dual-polarization configuration with a conical guide and slots to enhance signal robustness and decoupling, allowing for single-antenna operation across long ranges and varying weather.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If E-band antennas are used for high-frequency transmissions, then data transmission capacity is improved, but signal attenuation increases over long distances and in adverse weather conditions
Solution Approach 1:
The patent combines E-band and lower frequency transmission capabilities into a single antenna system. The antenna is designed to operate simultaneously in both frequency ranges, merging the high-capacity E-band transmission with the more reliable lower frequency transmission that penetrates adverse weather conditions better, thus resolving the contradiction between data capacity and transmission reliability
Solution Approach 2:
The antenna is designed with multi-functionality to operate across multiple frequency bands (E-band and lower frequencies). This universal design allows the single antenna to provide both high-capacity transmission when conditions permit and reliable transmission when adverse weather affects higher frequencies, eliminating the need for separate dedicated antennas for each frequency range
2Reliability
If a second antenna is added for lower frequency transmissions, then transmission robustness is improved, but equipment costs and installation complexity increase
Solution Approach 1:
Instead of using separate antennas for E-band and lower frequency transmissions, the patent merges both transmission capabilities into a single multi-band antenna system. This consolidation reduces equipment complexity and installation requirements while maintaining transmission robustness across different weather conditions through the lower frequency capability
Solution Approach 2:
The single antenna is designed with universal functionality to handle both E-band and lower frequency transmissions. This multi-functional design eliminates the need for multiple specialized antennas, thereby reducing device complexity and installation complexity while ensuring transmission robustness through frequency diversity
3Reliability
If a second antenna is added for lower frequency transmissions, then transmission robustness is improved, but installation space requirements increase
Solution Approach 1:
The patent merges the functionality of what would traditionally require two separate antennas into a single integrated antenna system. By combining E-band and lower frequency transmission capabilities in one antenna, the mounting space requirement is significantly reduced while maintaining transmission robustness through the lower frequency capability that performs better in adverse weather
