Solution Overview
Problem
The increasing number of antennas in user devices for multiple communication protocols occupies valuable space and causes interference with other components, affecting performance, especially when in close proximity to the human body.
Innovation Solution
A multi-layer antenna system is created by forming a surface pattern with pits on a material layer, filling the pits with a material of different dielectric constant, and using a wave launcher to couple energy, allowing for efficient radiation and reception of signals across various frequencies without the need for multiple physical antennas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple physical antennas are embedded in user devices to support multiple communication protocols, then communication functionality is improved, but device space is occupied and interference with other components increases
Solution Approach 1:
The patent combines multiple antenna functions into a single integrated structure. The base layer with its specific geometry (circular, square, or rectangular shape) serves as a common platform that supports multiple communication protocols through frequency-selective surfaces and resonant structures, eliminating the need for multiple separate physical antennas
Solution Approach 2:
The base layer antenna structure is designed to perform multiple functions simultaneously. By incorporating frequency-selective surfaces and adjusting geometric parameters, the same antenna structure can operate across different frequency bands (e.g., 2.4 GHz, 5.8 GHz, 60 GHz), making it a universal solution for various communication protocols
2Volume of moving object
If multiple antennas are packed closely together to reduce device size, then device compactness is improved, but antenna performance deteriorates due to interference
Solution Approach 1:
The patent applies local quality by creating frequency-selective surfaces with specific geometric patterns at different locations on the base layer. Each region of the base layer can be optimized for specific frequency ranges, allowing multiple communication functions to coexist without interference while maintaining compact device size
3Ease of operation
If antennas are placed in close proximity to human body parts, then device portability is improved, but antenna performance is seriously affected
Solution Approach 1:
The base layer structure acts as an intermediary between the antenna elements and the human body. The specific geometric design and material properties of the base layer help isolate the antenna from body effects, reducing performance degradation while maintaining the device's ability to be used in close proximity to the body

Data Source
AI summary
A dielectric material antenna is disclosed. The antenna includes a first material layer made up of a first material with a low dielectric constant. A surface pattern containing pits is carved out of the first material layer. The pits carved out are then filled up with a second material layer made up of a second material that has a high dielectric constant than the first material layer to form a first antenna layer. A wave launcher is provided near to the first antenna layer with a ground provided at its bottom. The wave launcher helps to couple the energy generated from an energy source to the first antenna layer in order to radiate and receive signals.
