Overview

The dual-band internal ceramic antenna is a high-performance antenna solution that combines the excellent properties of ceramic materials with dual-band working capabilities. It is widely used in multiple fields and plays an important role in wireless communications and navigation and positioning.

Key Features

• Good frequency stability

The dual-band built-in ceramic antenna can maintain its operating frequency unchanged over a large temperature range, which is very suitable for high-precision measurement, positioning and other fields.

• Strong anti-interference ability

Due to the use of ceramic materials, the antenna has a high anti-interference ability, which can effectively resist external interference and ensure the stability and reliability of the signal.

• Miniaturization and high integration

The dual-band built-in ceramic antenna has a small size and weight, which is easy to install and integrate inside the device, improving the overall aesthetics and portability of the device.

• High temperature resistance and weather resistance

The ceramic material has good high temperature resistance and weather resistance, allowing the antenna to maintain normal operation in harsh environments.
