RF Antennas
Radio frequency antennas (RF antennas) are key components for transmitting and receiving wireless signals, enabling long-distance data transmission through electromagnetic wave conversion. Modern technology enables them to cover a wide frequency band, from MHz to GHz, making them suitable for cutting-edge fields such as 5G, the Internet of Things (IoT), and satellite communications.
1. What are the Core Technical Parameters of RF Antennas?
Frequency Range: Customized design meets requirements from Sub-6GHz to millimeter wave frequency bands.
Gain: Adjustable from 3-15dBi to ensure directional signal transmission efficiency.
Polarization: Supports linear and circular polarization, adaptable to complex environments.
Impedance Matching: Standard 50Ω interface, compatible with mainstream RF circuits.
2. What are the Typical Application Scenarios of RF Antennas?
Smart Home: Wi-Fi 6E router antenna array.
Industrial IoT: LoRaWAN wide-area network coverage antenna.
In-Vehicle Communications: V2X high-gain antenna module.
3. Selection Recommendations for RF Antennas
Select the gain level based on the transmission distance (8dBi outdoors).
Circularly polarized antennas are preferred in multipath interference environments.
Radiation efficiency must be verified through OTA testing (≥70%).
4. Technology Development Trends of RF Antennas
Phased array antennas and MIMO (Multi-Input, Multiple-Output) technology are driving antennas towards miniaturization and intelligence. By 2025, the next generation of ceramic dielectric antennas will reduce power consumption by 30%.
