Antenova is announcing the Weii, a miniature ceramic antenna for all 2.4GHz, Bluetooth, WiFi, Zigbee and industrial, scientific and medical applications. While all of Antenova’s antennas and antenna module products are small surface mounted devices, this antenna is the smallest that Antenova has created so far. It is designed specifically for the consumer, IoT and M2M markets and measures just 1.00x0.5x0.5mm.

The Weii is an omni-directional, SMD mounted dielectric antenna that can be used to add wireless connectivity to any small electronic device, for example wearables, headsets, medical devices, PNDs, dongles and sensors.

A ceramic antenna offers several advantages for these emerging applications. Its extraordinarily tiny footprint is suitable for the scaled-down PCBs that are being developed for consumer devices in M2M. It offers a highly efficient antenna that is powerful over indoor ranges and performs well when situated close to the human body.

Antenova takes a unique approach to the design of antennas, which it calls 'Design For Integration'. As the antennas are always embedded within a customer’s design, the successful operation of the customer’s device depends upon obtaining the correct performance from the antenna when it is placed on the PCB, therefore Antenova is designing its antennas with this difficult RF integration in mind.

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 simply be dropped into the design, using CAD footprint files which are provided free of charge. To ensure that customers can harness the antenna successfully and achieve the optimal performance of the antenna, Antenova provides engineering assistance along with advice on RF design layout and the integration of the antenna, as well as customer support.
