A ceramic antenna is a compact, high-performance antenna made from ceramic dielectric materials. It is commonly used in wireless applications such as GPS, Wi-Fi, Bluetooth, and RFID due to its small size, durability, and high-frequency stability. These antennas operate based on dielectric resonance principles, where the ceramic material enhances signal reception and transmission efficiency.
