一、Features & Descriptions
Ceramic antennas (also known as dielectric antennas or GPS/BD antennas) are small-sized antennas made of ceramic material as the dielectric substrate. They function to transmit and receive signals and are used to reduce the size of the antenna while maintaining good electrical performance by taking advantage of the much higher dielectric constant of ceramic materials compared to ordinary PCB boards. Ceramic antennas are widely used in devices in the field of wireless communication in scenarios that require miniaturization and high performance. Ceramic antennas have the advantages of high gain, good directionality, good stability, strong anti-interference ability, good environmental adaptability, small size, and easy assembly. However, they also have disadvantages such as high cost, narrow bandwidth, and strict installation requirements, making them more suitable for scenarios with strict requirements for size and reliability.

三、Notes & Applications
Ceramic antennas are widely used in satellite navigation, Internet of Things, short-range wireless communication, vehicle electronics, radio frequency identification, mapping, navigation, time synchronization, and other fields due to their unique performance advantages, and have become the preferred solution for high-precision positioning and miniature wireless devices. During installation, a complete grounding plane is required, and it should be kept away from metal objects and noise interference sources; otherwise, the performance will be greatly reduced. During transportation, avoid severe impacts to prevent the ceramic blocks inside from cracking. It is recommended to wipe with alcohol during cleaning. The product should be stored in a warehouse with an ambient temperature of -10℃ to 40℃, a relative humidity of no more than 80%, no acidic, alkaline or other harmful gases in the surrounding environment.
