　　**

　　In fields such as RF testing and electromagnetic compatibility (EMC) testing that require extremely high signal accuracy, the 700 MHz double-ridged horn antenna has become an indispensable core device in professional scenarios with its unique technical design and excellent performance. It breaks through the performance limitations of traditional antennas and provides a stable and reliable signal carrier for high-precision RF applications.

　　1. Core performance: precise experience brought by technological breakthroughs

　　Ultra-wideband coverage capability: The double-ridged structure is the core technical highlight of the antenna. By designing symmetrical double-ridged loading on the inner wall of the horn, the operating frequency band is successfully expanded to a wide frequency range of 700 MHz and above, perfectly covering multiple key frequency bands such as LTE and RF testing. This design breaks the bandwidth limitation of traditional single-ridged antennas, realizes seamless signal transmission from low frequency to high frequency, meets the testing needs of multiple standards and multiple scenarios, and allows one device to handle test tasks in multiple frequency bands.

　　High gain and low standing wave ratio: In the 700 MHz core frequency band, the antenna gain is stably maintained at more than 8 dBi, ensuring that the signal has low attenuation and high strength during transmission. At the same time, the standing wave ratio (VSWR) is strictly controlled below 2.0, which means that the impedance matching between the antenna and the transmission line is extremely high, effectively reducing the signal reflection loss, so that every bit of signal energy can be efficiently utilized, providing a solid guarantee for the accuracy of the test data.

　　Directional radiation and high directivity: The horn-mouth gradient design is adopted to enable the antenna to have a strong directional radiation capability. The half-power lobe width is controlled at 60°-90° in the horizontal direction and 30°-60° in the vertical direction, which can accurately focus the signal energy. This feature enables it to accurately locate the interference source in electromagnetic interference testing, and to achieve point-to-point accurate signal transmission in the antenna calibration scenario, greatly improving the test efficiency and accuracy.

　　Sturdy and durable structural design: The antenna body is made of high-quality aluminum alloy material, and after surface electroplating, it is not only light in weight and high in strength, but also has excellent corrosion and oxidation resistance. The rounded corners of the horn mouth not only avoid edge diffraction interference in signal transmission, but also enhance the safety of the equipment. Whether it is long-term fixed use in the laboratory or outdoor mobile testing, it can maintain stable performance.

　　2. Professional scenarios: tailored for high-precision needs

　　Electromagnetic compatibility (EMC) test: In the EMC certification test of electronic equipment, the 700 MHz double-ridged horn antenna is the preferred equipment for radiation emission test and radiation immunity test. It can accurately receive the electromagnetic radiation signal emitted by the equipment, or simulate the impact of external electromagnetic interference on the equipment, helping testers to quickly determine whether the equipment meets the electromagnetic compatibility standards and ensure the stable operation of the product in a complex electromagnetic environment.

　　Antenna performance calibration: As a standard gain antenna, it is often used for performance calibration of other antennas. On the antenna production line, by comparing the signal with the antenna under test, it can quickly detect whether the key parameters such as the antenna gain and directional pattern meet the standards, providing an authoritative reference for the quality control of antenna products.

　　RF module research and development: In the research and development process of 5G base station RF modules, IoT communication modules, etc., the antenna can provide a stable signal source and receiving carrier for the module's transmission power, receiving sensitivity and other indicators. With its precise signal transmission capability, R&D personnel can quickly locate module design defects and accelerate product iteration and upgrading.

　　Radar and remote sensing systems: In small radar systems and remote sensing equipment, the 700 MHz double-ridged horn antenna can efficiently receive and transmit radar signals with its wide bandwidth and high directivity, helping to achieve accurate detection and data collection of targets, and plays an important role in meteorological monitoring, geological exploration and other fields.

　　3. Technical value: performance guarantee in professional fields

　　The technical advantages of the 700 MHz double-ridged horn antenna make it a key bridge connecting theoretical testing and practical applications. In professional fields that pursue data accuracy, it provides strong technical support for scientific research experiments, product testing, equipment development and other work with its stable performance and reliable performance.

　　With the in-depth application of RF technology in communications, aerospace, medical electronics and other fields, the demand for high-precision antennas will continue to grow. With its irreplaceable professional performance, the 700 MHz double-ridged horn antenna will surely shine in more high-end technology scenarios and inject continuous power into technological innovation and industrial upgrading.

　　Whether it is precision testing in the laboratory or quality control of the production line, choosing the 700 MHz double-ridged horn antenna means choosing precision, efficiency and reliability. It is a trustworthy RF signal solution in the professional field.
