Are you struggling to integrate a highly efficient sub-GHz antenna into a compact IoT device? Johanson Technology provides the solution: The 0900AT47A0063001E, a ceramic SMD chip antenna in an ultra-compact 10 × 3 × 2 mm format, optimised for the 868 MHz and 902–928 MHz ISM bands.

This antenna is perfectly suited for sub-GHz IoT applications such as LoRaWAN, Zigbee, Smart Agriculture, Asset Tracking, and other low-power designs. Thanks to state-of-the-art LTCC technology, it offers excellent radiation efficiency and resilience against detuning – even in unknown or challenging material environments.

Why Johanson Antennas for Sub-GHz?

• Detuning Resistance – due to LTCC construction with thermal stability (~2 ppm)

• High Efficiency – up to 68% average radiation efficiency on tuned layouts

• Small Format, High Performance – ideal for space-constrained designs
