David wither from sarantel talks about the growth in demand and higher margins


Sarantel (officially Sarantel Group PLC) (AIM: SLG) is a Wellingborough, UK-based manufacturer of miniature low-proximity antennas used in cell phones, PDAs, GPS, and other communication devices. The company has offices in England and the US. Sarantel is listed on the London Stock Exchange in the Alternative Investment Market (SLG.L).

Company history

Sarantel is a spin-off of Symmetricom founded in 2000 by Dr. Leisten. Leisten was spearheading the development of a new type of miniature antenna – now called PowerHelix - since the 1990s at Navstar Systems Ltd. Navstar was acquired by Symmetricom in 1993. During 1999 and 2000 Symmetricom enacted a strategy to focus on their core business of designing and manufacturing timing and network synchronization technology. They offered Dr. Leisten an opportunity to do a management buy out of the miniature antenna technology they acquired from Navstar.

Leisten took advantage of the offer and founded Sarantel and the company started trading on 29 September 2000 with first-round funding of approximately $10 million from 3i and Foresight Venture Partners. Further private funding rounds involved 3i, MTI, Foresight Venture Partners, Trivest, E Technologies and Hotbed In 2004 the European Tech Tour identified Sarantel as one of the Top 25 high growth technology companies in the UK. In March 2005 Sarantel floated on the London Stock Exchange's AIM market and in August 2005 Sarantel shipped its one-millionth antenna.

At 13 Jun 2013 the directors of Sarantel Limited have appointed PricewaterhouseCoopers LLP as an administrator to Sarantel Limited, the operating subsidiary of the Company. Since 20 Jun 2013 Sarantel has stopped business.

Japanese ceramic and electronic component manufacturer Maruwa acquired plant, machinery and intellectual property of Sarantel at the beginning of October 2013 and is manufacturing antenna products at its European headquarters in Ashford Kent. .<http://www.aimmicro.com/blog/entry/sarantel-group5/> http://www.maruwa-g.com/e/products/

Intellectual property

Sarantel has developed an intellectual property portfolio comprising over two dozen core patents with hundreds of international filings on the design and production of dielectrically loaded antennas.

Products and services

Sarantel’s antenna products are used in a broad range of GPS, satellite radio, military and satellite phone applications (see Applications).

The company’s primary focus is on designing and manufacturing patented dielectrically loaded antenna technology, this technology is specifically aimed at hand held devices which are mostly used close to human bodies. By off setting the antenna tuning to factor in the near-field interference caused by the water in the human body, Sarantel claims to reduce the impact of ‘body loading’ often associated with conventional antenna technologies. This however has the side effect of making the Helix type antennas less suitable for use in free space applications where a large watery body is not nearby.

Their R&D efforts are mostly focused on reducing near-field interference to improve the range and quality of wireless communications.

Technology

Sarantel’s PowerHelix antenna technology is the commercialization of 20 years of research in balancing electric fields across a dielectric-core. Their technology enables dense electro-magnetic near-fields to be stored in a low-loss dielectric material. This approach reduces the amount of close-range electromagnetic energy that a user of a cell phone, GPS or other mobile technology is exposed to.

Sarantel’s technology is geared towards applications of wireless antenna’s with "in-use" conditions where match and gain characteristics do not vary with changing use scenarios and towards applications that experience significant near-field interference.

In certain applications, antennas for wireless products that are used close to the human body should be designed resonating independently from the wireless product. This approach reduces the interference from human bodies called ‘body loading’ by removing the regions of high electro-magnetic field density from the areas that are occupied by human tissues when the wireless product is "in use". This method reduces the aperture size of the antenna and achieves a higher degree of electrical stability in the presence of the human body. It also reduces in-band "common-mode" noise from conducted power on the device chassis so that the approach also enables integration of multiple radios into a smaller device with reduced interference.

Sarantel’s topology and feed system is designed to provide electromagnetic isolation, rather than to resonate with the box as is the case with most conventional antennas.

Sarantel also provides MIMO solutions for mobile WiMax, 3G-LTE and WiFi IEEE802.11n where high data throughput and range depend on the isolation between the multiplicity of receiving and transmitting antennas on the box.

The manufacturing process

Sarantel has manufactured their own products since the company’s formation in 2000 using a highly accurate three-dimensional photolithography process.

In 2008, the company finalized the development of its 3rd generation production process. With each generation the company improves scalability of the process and lowers the cost of production.

Applications

Sarantel’s antennas exist inside the following types of applications:
