Smart antennas are divided into switch beams (such as 6-beam switching, response <5ms) and adaptive arrays (MIMO technology, beamforming gain up to 20dB). The former presets a fixed coverage direction, while the latter tracks users in real time and dynamically adjusts the phase, which can increase the capacity of 5G systems by more than 30%. […]

Dual antennas can work together (such as MIMO or relay), and need to be in the same frequency band (e.g. 2.4GHz±50MHz), with a spacing ≥ half a wavelength (6.25cm at 2.4GHz). Orthogonal polarization or isolator (isolation>20dB) to prevent interference, phase shifter to adjust the phase (within ±30°), combiner needs 50Ω impedance matching to ensure signal

Bigger antennas offer higher gain and directivity, enhancing signal strength and precision in target signal capture. Relationship Between Wavelength and Antenna Size An antenna’s size is directly linked to the wavelength of the signals it is designed to receive or emit. The rule of thumb in antenna design is that the effective size of an

The parabolic antenna offers the highest gain, typically exceeding 30 dB, focusing signals into a narrow beam. Directional Antennas and Gain Directional antennas are those that focus energy in directions designed to enhance the signal power and reception quality, and, as a result, significantly increase the antenna gain. The advantage of using this type of

No, coaxial cables and antennas are not the same. Coaxials transmit signals via cable, while antennas emit signals through air. Common Uses of Coaxial Cables in Telecommunications Coaxial cables are indispensable in many telecommunications applications because they can move immense amounts of data with minimal interference or loss. They play a crucial role in connection

Satellite antennas vary in size, such as Ku-band flat antennas with a diameter of about 0.45 meters, while C-band parabolic antennas can reach a diameter of 2 to 3 meters. The size should be selected based on the frequency, gain requirements and application scenarios. When installing, make sure to align with the satellite to maximize

The best antenna for satellite communication is a phased array antenna due to its rapid beam steering and wide frequency range capabilities. Parabolic Reflectors Parabolic reflectors are one of the most important components of satellite communications, mainly because they allow focusing radio waves into a narrow beam. These antennas use an appropriately shaped rounded reflective

Antennas are used to transmit or receive electromagnetic wave signals, such as mobile phone antennas with a frequency range of 800MHz to 2.6GHz. Satellites are devices that operate in orbit and can forward radio signals. For example, communication satellites can cover about 90% of the world and provide television and telephone services. Antenna Functionality At

Satellite communication antenna types include: parabolic antenna (usually 1.2 meters in diameter, suitable for C band), flat antenna (light and thin, suitable for Ku band), helical antenna (supports circular polarization), phased array antenna (can electronically control the beam direction) and portable antenna (easy to deploy, about 0.6 meters in diameter). Choose the appropriate type according
