Antennas are compact RF components designed to transmit and receive wireless signals while fitting within space-constrained electronic designs. They enable reliable wireless connectivity for technologies such as Wi-Fi, Bluetooth, cellular, GPS/GNSS, NFC, RFID, and other radio-frequency communication systems.

Available in various types, including chip, PCB, embedded, wire, flexible, and internal antennas, these components are designed to provide efficient RF performance while minimizing the space required within the device. Key considerations include operating frequency, impedance, gain, radiation pattern, bandwidth, and installation environment. They are commonly used in smartphones, tablets, wearables, IoT devices, sensors, smart home equipment, portable electronics, tracking devices, and other compact wireless products.
