SMT Ceramic Antenna

Overview

The patch ceramic antenna is a miniaturized and lightweight antenna that uses ceramic material as the base. The antenna pattern is printed or embedded in the ceramic through a specific process and is made through sintering and other processes.The patch ceramic antenna can cover a wide range of frequency bands, including GSM, UMTS, LTE, Wi-Fi, Bluetooth, etc., and supports multiple polarization modes and radiation modes.

Key Features

• Miniaturization and Lightweight

The patch ceramic antenna has a small body and light weight, which is very suitable for the strict requirements of modern communication equipment on space and weight.

• Excellent heat dissipation performance

Ceramic materials have good heat dissipation performance, which helps the antenna maintain stable performance during long-term operation.

• Strong anti-interference ability

During the design and manufacturing process, the patch ceramic antenna improves its anti-interference ability by optimizing the antenna structure and materials to ensure the stable transmission of communication signals.

• High temperature resistance

It can withstand high temperatures of 200~300 degrees without deformation, which is difficult for ordinary metal antennas to do.

• Good conductivity

Good thermal stability and chemical stability, not easily corroded by acids and alkalis.

Specification

Antenna thickness, frequency, polarization mode & soldering pad can be customized.
