AI Technical Summary
Technical Problem
When the next generation of wireless communication technology uses millimeter wave array antennas, reflections from the metal frame cause the antenna beam to deflect, reducing performance, and heat is difficult to radiate effectively, affecting data transmission efficiency.
Method used
A dielectric sheet with a combination of low and high dielectric constants is placed between the antenna module and the metal frame structure to reduce the impact of the metal frame and effectively radiate heat.
Benefits of technology
The antenna coverage is improved, beam coverage in the direction of the line of sight is ensured, and heat radiation efficiency is increased, solving the negative impact of the metal frame on antenna performance.
