The professional terms for antennas include: RF system antenna type, operating frequency band, antenna gain, antenna structure, standing wave ratio, maximum input power (transmitter), and so on. In the field of wireless communication, antennas play a crucial role. They are responsible for receiving and transmitting wireless signals by converting them into electromagnetic waves for transmission. The design and application of antennas involve various professional terms and parameters.

Firstly, RF system antenna types refer to the classification of different antennas. Common types include directional antennas, omnidirectional antennas, sector antennas, and patch antennas. Different types of antennas have different radiation characteristics and usage scenarios. For example, directional antennas are suitable for long-distance communication, while omnidirectional antennas are suitable for wide coverage communication needs.

Secondly, the operating frequency band of an antenna refers to the frequency range in which the antenna can work effectively. It varies depending on the application. For instance, WiFi antennas commonly operate at 2.4GHz or 5GHz, while LTE antennas usually cover the frequency range from 700MHz to 2.7GHz.

Antenna gain is a measure of the power intensity radiated by an antenna and is usually expressed in dBi units. Antenna gain depends on the antenna's structure and design. Higher-gain antennas can achieve longer distance communication, but the impact of antenna directivity on coverage range also needs to be considered.

The antenna structure includes Marconi antennas, dipole antennas, helical antennas, and more. Different antenna structures are suitable for different frequency bands and application requirements. For example, Marconi antennas are suitable for wideband communication, while helical antennas are suitable for satellite communication and other special scenarios.

Voltage Standing Wave Ratio (VSWR) is a parameter that describes the degree of impedance matching at the input port of an antenna. A lower VSWR indicates better impedance match between the antenna and the transmission line, maximizing the transmission of signal energy.

Power handling capacity refers to the maximum power that an antenna can withstand. The design and material selection of an antenna affect its power handling capability. In high-power applications, it is necessary to choose antennas with sufficient power handling capacity to ensure reliability and stability.

In conclusion, antennas play a crucial role in wireless communication systems. Understanding professional terms and parameters such as RF system antenna types, operating frequency range, antenna gain, antenna structure, VSWR, and power handling capacity helps to deepen the understanding and application of antenna technology, thereby optimizing the performance and coverage range of communication systems.
