Antenova targets three antenna families at M2M and IoT

UK antenna maker Antenova has announced three families of antennas that use different design approaches for the M2M, wearable technology and IoT markets. Several antennas from each family are to be released during 2015, with the first, a miniature ceramic antenna, available this month.
 
Each of the three families comprises embedded antennas of a particular style, and they are to be marketed with three distinctive brand names – LamiiAnt, CeriiAnt and FlexiiAnt.
 
LamiiAnt antennas are made from FR4 materials. These SMD antennas use the latest in dielectric constant laminate substrates. They are suitable for all wireless applications from 680 to 2700MHz, including Bluetooth, Wifi, Zigbee, ISM, cellular, LTE and GNSS.
 
CeriiAnt miniature ceramic antennas have been scaled down to small sizes and perform well close to the human body. They are suitable for connected consumer devices, wearable technology and M2M applications.
 
FlexiiAnt is a group of flexible FPC antennas, with a cable and connector that are attached to the underside covering or housing of a users’ product. They can be used in any wireless electronic market.
 
The three families will be used in consumer applications such as connected watches, tracking technology and fitness devices, and will also have commercial applications in industry, automotive design, security and environmental controls. 
 
“Antenova is experiencing a surge of projects using embedded wireless in M2M, IoT and connected devices,” said Colin Newman, director and VP of sales at Antenova M2M. “We are working with the very latest technologies and materials available today to develop solutions that address these high growth markets, and meet the challenges of creating designs for these new wireless applications.”

• Antenova has also announced its first antenna for consumer applications – the Weii 2.4GHz ceramic antenna, which it says is possibly the smallest antenna in the world. It is for for Bluetooth, Wifi, Zigbee and ISM applications. For consumer, IoT and M2M markets, it measures 1.00 by 0.5 by 0.5mm.

"Ceramic antennas offer low dielectric losses and high isolation,” said Newman. “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."

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.

Its tiny footprint is suitable for scaled-down PCBs being developed for consumer devices in M2M. Its efficient antenna is powerful over indoor ranges, and performs well when sited close to the human body.

Because the antennas are always embedded within a user's design, the successful operation of the device depends on obtaining the correct performance from the antenna when it is placed on the PCB, therefore Antenova designs its antennas with this RF integration in mind.

The Weii can be integrated into all kinds of PCB designs and various ground plane sizes – it has been engineered so it can be dropped into the design using cad footprint files, which are provided free of charge. Engineering assistance is provided along with advice on RF design layout and the integration of the antenna.
