1mm x 0.5mm x 0.5mm unit can add wireless connectivity to any small electronic device

Is this the smallest antenna for wearables?

An antenna manufacturer has unveiled what it’s calling the smallest antenna in the world for small electronic devices such as wearable tech, headsets and Internet of Things (IoT) sensors.

Antenova has announced the Weii 2.4GHz ceramic antenna, which measures 1mm x 0.5mm x 0.5mm and is designed for all 2.4GHz, Bluetooth, Wi-Fi, Zigbee and ISM applications.

It is designed specifically for the consumer, IoT and Machine-to-Machine (M2M) markets, and the omni-directional, SMD mounted dielectric antenna can be used to add wireless connectivity to any small electronic device, for example wearables, headsets, medical devices, PNDs, dongles and sensors.

Antenova says the ceramic antenna is ideal for the new, scaled-down PCBs that are being developed for consumer devices in M2M, and is ‘powerful’ over indoor ranges.

The Weii is designed to be easily integrated into all kinds of PCB designs and various ground plane sizes – it has been engineered so that it can be dropped into the design using free CAD footprint files.

Antenova’s Director and VP of Sales, Colin Newman, said: “Ceramic antennas offer low dielectric losses and high isolation. Our engineers have used this technology to greatly reduce the antenna volume without sacrificing performance.

"The challenge in building antennas for today’s small consumer devices is to achieve high isolation and frequency selectivity while maintaining good efficiency. This antenna is resistant to detuning from environmental effects, and combining this with its ultra-small size, makes it ideal for today’s wearable products."
