How to Choose the Right Antenna for Your IoT Device?

Selecting an antenna for IoT devices involves balancing size, frequency, and environment. Here’s a quick guide:

• Frequency Needs:
• Sub-GHz (e.g., 868MHz, 915MHz) for long-range, low-power applications.
• 2.4GHz/5GHz for high-speed data (Wi-Fi/BLE).
• Antenna Types:
• PCB Antennas: Low-cost, ideal for compact designs.
• Ceramic Antennas: High efficiency in small footprints.
• External Antennas: Better performance in metal-rich environments.
• Key Tests:
• TRP/TIS (Total Radiated Power/Isotropy) for real-world performance.
• SAR (Specific Absorption Rate) for wearable safety.
