IoT Antenna Guide: How to Choose the Right Internal or External Antenna for Your IoT Project

Introduction:

As the Internet of Things (IoT) continues developed at our smart cities at many area, weather develop a GPS tracker, industrial gateway, smart meter, asset tracking device, or vehicle telematics system, selecting a right antenna can significantly improve signal efficiency and device performance.

Why Is the Antenna Important in IoT Devices?

The antenna is the bridge between device and the wireless network, it have big effect on advanced communication module. 

Internal Antenna vs. External Antenna advantage

Compact design space saving       Better appearance

Lower risk of external damage    cheaper cost  waterproof  products

Why work with experienced manufacturer

Comprehensive testing equipment such as vector network analyzers, anechoic chambers, and environmental reliability tests help ensure stable performance before shipment. 

External antennas fit for connected via SMA,Fakra, MMCX, U.FL, or custom RF connector with device
