The operating frequency of an antenna refers to the frequency range within which the antenna can operate or receive signals. The frequency range of an antenna depends on its design and intended use. The following are several common antenna operating frequencies and related reference contents:
1.Low-frequency antenna:
Low-frequency antennas are mainly used to receive amplitude modulation (AM) broadcasts, longwave, and low-frequency radio signals. Their operating frequency range is usually between 30 kHz and 300 kHz. These antennas can be long-wire antennas, truss antennas, or loop antennas.
2.Medium-frequency antenna:
Medium-frequency antennas are usually used to receive amplitude modulation (AM) broadcasts, shortwave, and medium-wave radio signals. Their operating frequency range is usually between 300 kHz and 3 MHz. Common medium-frequency antennas include vertical radio frequency antennas and horizontal radio frequency antennas.
3.High-frequency antenna:
High-frequency antennas are mainly used to receive amplitude modulation (AM) broadcasts, shortwave, and high-frequency radio signals. Their operating frequency range is usually between 3 MHz and 30 MHz. High-frequency antennas can be vertical antennas, horizontal antennas, log-periodic antennas, or curtain antennas.
4.Ultra-high frequency (UHF) antenna:
UHF antennas are used to receive UHF broadcasts, television, wireless networks, and satellite communication signals. Their operating frequency range is usually between 300 MHz and 3 GHz. Common UHF antennas include dipole antennas, helical antennas, and tangential antennas.
5.Millimeter-wave antenna:
Millimeter-wave antennas are mainly used to receive wireless communication signals in the millimeter-wave frequency band, and their operating frequency range is usually between 30 GHz and 300 GHz. Millimeter-wave antennas can be microstrip antennas, corner column antennas, or array antennas.
To sum up, the operating frequency range of antennas ranges from low frequency to millimeter-wave frequency band. The frequency range of an antenna is closely related to its design and purpose. The several antenna operating frequencies mentioned above are only some common ranges, and in fact, there are broader options for the frequency range of antennas.
