EnglishUHF antennas are signal transceivers specifically designed for the Ultra High Frequency (UHF) band, operating in the 300-3000MHz range. They are ideal for short-range, high-speed communication and multi-scenario wireless transmission, making them core components in consumer electronics, industrial communication, and urban services. They are also one of the most popular antenna categories.
Key Parameters:
Frequency Range: Standard UHF band 300-3000MHz, core civilian sub-bands (e.g., 2.4GHz WiFi/Bluetooth, 5.8GHz video transmission, 470-862MHz digital TV, RFID 860-960MHz).
Input Impedance: Mainstream is 50Ω (compatible with communication equipment, routers, walkie-talkies), some TV UHF antennas use 75Ω to ensure lossless signal transmission.
Polarization: Primarily vertical polarization (e.g., built-in mobile phone antennas, vehicle antennas) and horizontal polarization (e.g., Yagi antennas for televisions), with some high-end models supporting ±45° slant polarization (for stronger anti-interference).
Gain: Standard gain is 2-12 dBi. Directional antennas (e.g., plate antennas, Yagi antennas) can reach over 15 dBi, while omnidirectional antennas (e.g., stick antennas) have a gain of 2-5 dBi, adapting to different coverage requirements.
Common Types: Omnidirectional antennas (whip, stick), directional antennas (Yagi, plate, parabolic), patch antennas (built-in), helical antennas (for circular polarization scenarios).
