　　1. Professional Omnidirectional 2.4G Frequency Band Design: Adapt to IoT Communication Core Needs. Our R&D team is composed of senior RF (Radio Frequency) engineers and IoT technology experts with rich experience in wireless communication components. The design focuses on 2.4G frequency band optimization, omnidirectional signal coverage and communication stability. The antenna adopts a professional dipole antenna structure, which is precisely tuned to the 2.4G Hz ISM frequency band (2.400-2.4835 GHz), matching mainstream IoT wireless protocols such as Wi-Fi (802.11b/g/n), Bluetooth, ZigBee and LoRa. The omnidirectional radiation design ensures 360° uniform signal coverage with a horizontal coverage angle of 360° and a vertical coverage angle of 120°, effectively eliminating signal blind spots. The integrated impedance matching circuit (50Ω standard impedance) realizes low standing wave ratio (VSWR ≤1.5), reducing signal reflection and ensuring high signal transmission efficiency (gain up to 3dBi). Meanwhile, the antenna supports plug-and-play installation with various standard interfaces, facilitating quick integration with IoT devices.

　　2. High-Quality Material Selection: Foundation of Durability & Stable Performance. We adhere to the principle of selecting high-performance materials from well-known international suppliers to ensure the reliability and durability of the antenna. The antenna radiation element is made of high-purity copper wire or tinned copper wire, which has excellent electrical conductivity and low signal loss, ensuring stable signal transmission. The shell is made of high-quality soft rubber material (TPR/TPE), which has excellent wear resistance, impact resistance and bending resistance, and can withstand frequent collision and bending without damage. For harsh environmental applications, we adopt UV-resistant and waterproof rubber materials (IP65 protection level optional), effectively resisting ultraviolet radiation, rain, dust and other environmental factors. The base is made of high-strength ABS plastic, which has good mechanical strength and stable installation performance. All materials undergo strict environmental adaptability testing and reliability testing to ensure long-term stable operation of the antenna in various complex IoT application environments.

　　3. Advanced Manufacturing & Calibration Technology: Guarantee of Communication Quality. Equipped with state-of-the-art RF component production lines, including high-precision automatic welding equipment, RF frequency tuning equipment, network analyzers and environmental testing equipment. We implement strict manufacturing processes, including material cutting, precision winding, component assembly, impedance matching calibration, shell injection molding and overall performance testing. The antenna radiation element is processed by precision winding technology to ensure consistent electrical performance parameters. Each antenna undergoes strict RF performance calibration, including frequency band accuracy testing, gain testing, standing wave ratio testing and signal transmission efficiency testing. We also conduct a series of environmental adaptability tests: high-low temperature testing (-40℃ to 85℃), humidity testing (95% RH), vibration testing and salt spray testing to ensure the antenna can adapt to extreme temperature changes, high humidity, vibration and corrosive environments. The professional assembly process ensures tight bonding between the shell and the internal components, preventing water and dust from entering.
