In the process of 5G network construction and communication antenna application, many industry partners often have some misunderstandings due to insufficient professional knowledge, which may lead to poor network performance, increased deployment costs, and even shortened antenna service life. Clarifying these common misunderstandings and mastering correct application methods is crucial to improving the efficiency of antenna application and ensuring stable network operation.
We sort out five common misunderstandings in communication antenna application and corresponding correct practices, helping industry partners avoid detours in practical work:
- Misunderstanding 1: Higher Gain Means Better Performance: Many people believe that the higher the antenna gain, the better the performance. In fact, gain is closely related to the coverage scenario: high-gain antennas have narrow coverage angles, suitable for remote long-distance coverage; low-gain antennas have wide coverage angles, suitable for indoor and dense urban areas. Blindly pursuing high gain will lead to uneven coverage and increased interference.
- Correct Practice: Select the appropriate gain according to the coverage distance and area. For example, remote areas choose high-gain antennas (16-18dBi), while indoor venues choose low-gain antennas (8-12dBi), ensuring that the coverage is uniform and free of blind spots.
- Misunderstanding 2: Antenna Installation Position Has No Impact on Performance: Some partners ignore the impact of installation position on antenna performance, randomly installing antennas in areas with obstacles or strong electromagnetic interference. This will lead to serious signal attenuation, poor coverage, and increased interference.
-Correct Practice: Choose an open, unobstructed installation position (such as the top of a high-rise building, the top of a pole) to avoid obstacles such as trees, buildings, and power lines; keep a certain distance from high-power electronic equipment to avoid electromagnetic interference.
- Misunderstanding 3: Ignoring Antenna Polarization Mode Matching: The polarization mode of the antenna (linear polarization, circular polarization) needs to match the base station and terminal equipment. Ignoring polarization matching will lead to serious signal attenuation and reduced transmission quality.
- Correct Practice: Confirm the polarization mode of the base station and terminal equipment, and select the corresponding antenna. For example, most 5G base stations use linear polarization antennas, so linear polarization antennas should be selected for matching to ensure stable signal transmission.
- Misunderstanding 4: Neglecting Antenna Maintenance: Many partners believe that antennas can be used for a long time without maintenance after installation. In fact, outdoor antennas are affected by harsh environments such as wind, rain, and dust, which will lead to reduced performance and even failure over time.
- Correct Practice: Regularly inspect the antenna’s appearance, connectors, and fixing parts, clean the antenna surface, check for water seepage and corrosion, and replace damaged parts in time to ensure the long-term stable operation of the antenna.
- Misunderstanding 5: Blindly Pursuing Multi-Band Integration: Multi-band integrated antennas have the advantage of reducing the number of antennas, but some partners blindly pursue multi-band integration regardless of their own needs, leading to increased costs and reduced performance of a single band.
- Correct Practice: Select the number of bands according to the actual network needs. If only a single 5G band is used, a single-band antenna can be selected to ensure optimal performance and cost savings; if multiple bands are needed, a multi-band integrated antenna can be selected on the premise of ensuring performance.
Mastering the correct application methods of communication antennas and avoiding common misunderstandings can effectively improve network performance, reduce costs, and extend the service life of antennas. We will continue to share professional application knowledge to help global partners better apply communication antennas.
