Broadband circular polarized slot antenna with low axial ratio

　　Broadband Circular Polarized Slot Antenna with Ultra-Low Axial Ratio

　　Your Reliable Partner for High-Performance Wireless Transmission

　　Core Advantages That Stand Out Globally

　　✅ Ultra-Wide Bandwidth Coverage

　　Engineered to support a broad frequency range (customizable from 1.5GHz to 6GHz, or as per your demand), this antenna eliminates the need for multiple devices in multi-standard systems—ideal for 5G, satellite communication, and IoT applications.

　　✅ Exceptionally Low Axial Ratio (<3dB)

　　The optimized slot structure and circular polarization design ensure an axial ratio below 3dB across the entire operating band. This minimizes polarization loss, enhances signal penetration through obstacles (e.g., buildings, weather interference), and guarantees stable, long-distance transmission.

　　✅ Compact & Easy Integration

　　With a low-profile slot design, the antenna occupies minimal space (typical size: 80mm×80mm×5mm, customizable) and fits seamlessly into drones, portable terminals, base stations, and consumer electronics. No complex installation—supports SMA, N-type, or custom connectors.

　　✅ High Gain & Anti-Interference

　　Boasts a gain of 8-12dBi (adjustable) for extended signal coverage, while the circular polarization suppresses cross-polar interference. Perfect for scenarios requiring reliable connectivity, such as maritime navigation, aerospace, and industrial IoT.
