Solution Overview
Problem
High-frequency wireless communication devices face signal attenuation and interference due to the challenges of transmitting and receiving radio frequency signals effectively at relatively high frequencies, such as 28 GHz or 60 GHz.
Innovation Solution
A semiconductor device package is designed with a substrate and dual antenna patterns of different bandwidths, where one antenna pattern generates a magnetic field, and the other is spaced apart to minimize interference, allowing for improved signal transmission and stability by using a conductive layer and dielectric layer configuration.

1Speed
If high frequency wireless transmission is used to achieve high data rate, then communication speed is improved, but signal attenuation and interference increase
Solution Approach 1:
The antenna system is divided into multiple antenna patterns with different bandwidths operating at different frequencies. This segmentation allows the system to transmit high-frequency signals for high data rates while using lower-frequency antenna patterns to provide stable reference signals, thereby maintaining signal quality despite the challenges of high-frequency transmission.
Solution Approach 2:
The patent employs antenna patterns with different bandwidth parameters to operate at different frequency ranges. By changing the operating frequency parameter across multiple antenna patterns, the system achieves high data rates through higher frequencies while maintaining reliability through lower frequency patterns with broader bandwidths that provide stable communication.
2Area of stationary object
If multiple antenna patterns are placed close together to save space, then device compactness is improved, but mutual interference between antennas increases
Solution Approach 1:
Different regions of the substrate are assigned antenna patterns with different local characteristics - specifically, antenna patterns with different bandwidths and frequency ranges are placed in different locations. This local differentiation allows compact arrangement while minimizing interference, as each antenna operates in its optimized frequency range and spatial position.
Solution Approach 2:
The patent resolves spatial interference by introducing frequency dimensionality - antenna patterns are arranged not only in physical space but also across different frequency bands. This multi-dimensional arrangement allows compact packaging while maintaining signal integrity, as interference is minimized through frequency separation in addition to spatial separation.
