Technology

Overview

Since its founding in 2002, Deltenna has built up an extensive technology portfolio which it has applied to both its own product developments and developments carried out under contract for specific customers. This includes a portfolio of more than ten issued and pending patents in the fields of antennas and integrated wireless systems. We have also established close relationships with leading semiconductor manufacturers, often guiding them in the development of their next generation devices.

Deltenna has particular expertise in the development of antenna products and in the integration of these with radio systems, skill sets that are surprisingly rare in an industry where antennas, radios and baseband are often treated as completely separate entities. We have developed solutions for a wide variety of wireless standards, including GSM, WCDMA, WiMAX and WiFi. Our approach to the market is simple:

  1. We identify a need or limitation with existing technology or products.
  2. We develop an optimal solution by applying an end-to-end system approach and the disruptive use of technology.
  3. We prove it works and bring it to market. In the past this was often through licensing, but today our usual approach is to manufacture and sell our own product.

This approach has allowed us to develop products that meet a number of diverse criteria rather than using a “one size fits all” approach. Sometimes the requirement is for smaller size, sometimes for higher performance and sometimes for lower cost, or some combination of all of these. The requirement for our rugged antenna, for example, was for small size but also high performance, and of course the ability to withstand all kinds of harsh environments.

Antenna Design

Whatever testing is done in the lab, ultimate performance of an integrated radio and antenna depends on its surroundings when deployed. Do the signals propagate as expected and how might they affect nearby electronic equipment?

Deltenna uses tools for the Far-field Analysis of Integrated Structures (FAIS). The system uses powerful and accurate 64-bit numerical analysis running on large multi-processor computers. These enable full 3D electromagnetic modeling of structures at high frequencies from airplanes to mobile handsets. Advanced cell-reduction techniques enable radiating structures to be easily optimized and integrated.

With multiple antenna techniques such as Multiple-Input, Multiple-Output (MIMO) being used to enhance system performance, understanding the antenna and its environment is essential. FAIS highlights possible constraints: high coupling between co-located antennas or limited multipath in the channel. Both of these reduce data throughput and without a detailed simulation finding a solution is a matter of guesswork.

Using FAIS, far-field patterns and electromagnetic exposure can be accurately modeled, antenna de-tuning can be precisely simulated and propagation tools and models can be modified using data generated from a virtual environment.

Manufacturing

Having world beating designs is a necessary ingredient for a successful product, but it’s not sufficient. The product also needs to be made. In the design of any complex product, particularly those which contain complex antenna structures, it is also necessary to consider how it will be manufactured right from the start of the development process, or the result may be a product that meets all the necessary technical specification but is un-manufacturable, or at least un-manufacturable in volume for a price that enables it to be sold profitably.

Deltenna has built up a huge store of manufacturing knowledge, working closely with manufacturers both in the UK and further afield, depending on where particular processes are available economically.  We are adept at keeping costs to minimum whilst maintaining the highest quality standards. Some of our products are designed to be sold in tens, which means that much of the assembly will be done by hand, whereas others as designed to be sold in tens or hundreds of thousands, which means that the effort that we put into the development of the manufacturing processes and tooling can dominate the non-recurring costs.
