Solution Overview
Problem
Millimeter wave antenna apparatuses have low gain due to their fixed beam radiation direction, limiting their effectiveness in transmitting millimeter wave signals.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed direction millimeter wave antenna is used, then the structure is simple, but the gain is low
Solution Approach 1:
The patent changes the dielectric constant parameter of the rear housing material from uniform to gradient distribution. By creating a continuous variation in dielectric constant (a physical parameter), the antenna beam direction is dynamically adjusted without mechanical movement, resolving the contradiction between structural simplicity and signal gain improvement
Solution Approach 2:
The patent applies local quality by creating a gradient dielectric layer only in specific regions of the rear housing rather than uniformly throughout. This localized modification of material properties (different dielectric constants in different zones) enables beam steering functionality while maintaining overall structural simplicity
2Ease of manufacture
If the beam radiation direction is fixed, then the manufacturing is easy, but the transmission efficiency is low
Solution Approach 1:
The patent uses parameter changes by varying the dielectric constant throughout the rear housing material. This continuous parameter variation enables the antenna to control beam direction electronically through material properties rather than mechanical adjustment, maintaining ease of manufacture while improving transmission efficiency through optimized signal routing
Solution Approach 2:
The patent employs composite materials by combining the dielectric layer with the rear housing structure to create a gradient dielectric composite. This composite structure integrates beam steering functionality into the housing itself, simplifying manufacturing while enhancing transmission efficiency through coordinated material properties
