OnBoard™ SMD - Product release

Published den 20 februari 2014 16:32
Proant takes embedded antenna integration one step ahead by combining high performance and low cost in the new concept OnBoard™ SMD family.

Traditionally,small low cost antennas for Printed Circuit Board (PCB) assembly have been manufactured with some kind of dielectric substrate as base for the radiating structure. With this approach the antenna normally has the shape of a rectangular block, which results that all PCB surface below the antenna is prevented for use of other components. Another more obvious drawback is that the substrate itself introduces dielectric losses to the antenna and reduces the total efficiency.

Proant decided to take the concept of small SMD antennas one step ahead, with the focus to increase the performance and design flexibility in combination with low cost and manufacturability. The result is the OnBoard™ SMD antenna family which originates from the previous OnBoard™ antenna concept, but is a surfacemounted sheet metal antenna, packaged tape on reel why it is suitable for high volume manufacturing. One of the key features which eliminate the need of a dielectric substrate, used in other SMD antennas, is the capacitively loaded foot print of the supporting pins of the antenna (pending patent) that significantly reduces losses and increases the performance.

The first two products to be launched from this family are:
  • OnBoard™SMD 2400 (2.4GHz band)
  • OnBoard™SMD GPS (GPS and Glonass)

Several other variants are on its way, and planned to be released during 2014:
  • WLAN dual band
  • 868/915MHz
  • GSM

“We wanted to simplify antenna integration for our customers” says Tomas Rutfors, CEO of Proant.
“The solution was to make a simple product which satisfies both engineering and sourcing aspects. With the OnBoard™ SMD family, we have defined a new product segment which didn’t exist before.”
