AI Technical Summary

Technical Problem

Traditional radomes made from thermoplastic materials like PC have high dielectric constants, obstructing electromagnetic waves and leading to low transmission rates and poor antenna performance.

Method used

A radome design using a core layer with a low dielectric constant, sandwiched between two skin layers, eliminates the need for edge sealing, allowing the entire structure to serve as a radiation region and reducing dielectric constant.

Benefits of technology

Improves antenna performance and reduces radome size by minimizing dielectric interference and eliminating the need for edge sealing, while maintaining mechanical integrity.

Abstract

Provide are a radome, which comprises a radome body and a composite panel. The radome body is provided with a hollow region, which has a first opening and a second opening in a first direction. The first direction is a thickness direction of the radome body. The composite panel comprises a core layer, a first skin layer and a second skin layer. The core layer is embedded in the hollow region and has a first side and a second side opposite to each other in the first direction. The first skin layer is sealingly attached to the first side and covers the first opening. The second skin layer is sealingly attached to the second side and covers the second opening. The core layer is made of a low dielectric constant material, and the peripheral edge of the core layer extends to abut against the inner wall of the hollow region.
