Taiwanese firm Synzen Precision Technology has unveiled two low-profile antennas for the wearable market or any IoT devices that require a slim design.

Both Alcor and Atria have a height of 1.6mm.

Alcor is a 5G low-profile surface mount antenna that has been developed to be compact but still cover bands from 617 to 6000MHz. It has a footprint of 40 by 10 by 1.6mm and a fallback to 4G, 3G and 2G.

Atria is more compact but still covers bands from 698 to 2690MHz, and also falls back to 3G and 2G. It measures 30.0 by 7.0 by 1.6mm and requires a small clearance area.

“Many antennas calling themselves low-profile are double the height, around 3mm,” said Chris Tomlin, Synzen’s technical director. “We’ve been able to halve that without losing any performance. Our elegant design is also cost-effective for customers because it doesn’t require any external RF switch circuits.”

The clearance area for Alcor is 40.0 by 13.5mm and for Atria, which comes in left and right corner mount versions, is 30.0 by 12.0mm.

Alcor and Atria are suitable for mimo applications and are designed to work in compact devices with limited space. These antennas are suitable for wearables, health monitoring, smart meters and other slim IoT devices. They form part of Synzen’s Galaxy Class, which all feature low-profile designs.

Synzen Precision Technology is an antenna and module product design company based in Taipei. It provides advise on optimal placement and will optimise the tuning and offer free testing to characterise the performance. It says it can test and prove a design within a day, free of charge.
