상품 특징

• 【Ultra-Compact, Fully Embedded Design】 Only 5cm long—1/3 the size of standard antennas. Easily fits into tight spaces like smart lock battery compartments or sensor housings. Ideal for space-constrained applications where bulky antennas just won’t work.
• 【Precise 315MHz Tuning with 50Ω Matching】 Built-in miniaturized impedance matching system ensures accurate 50Ω tuning at 315MHz. VSWR ≤ 2.0, boosting transmission efficiency by 30% compared to conventional antennas of similar size.
• 【Gold-Plated SMA Connector for Stable Signal】 Features a right-angle SMA male connector with full gold plating. Low contact resistance (≤50mΩ) and insertion loss (≤0.3dB @ 315MHz), outperforming standard nickel-plated connectors for more stable high-frequency signal transmission.
• 【90° Right-Angle Design for Space Optimization】 Perfect for edge-mounting on PCBs or side ports of compact devices like smart plugs. The angled design avoids interference from surrounding components and ensures optimal orientation for better signal strength—up to 20% gain in real-world tests.
• 【Reliable Performance, Built to Last】 Designed for rugged use—supports 500+ plug/unplug cycles with no signal degradation. Lower contact resistance improves conductivity by 40%, making it ideal for frequent prototyping, debugging, or field adjustments.
