ANTENNA DESIGN

Why Antenna Design as a Turn-key Service?

Wireless connection is the most critical feature of your connected device. And, the antenna is the crucial component ensuring robust RF performance and superb user-experience. Yet, designing an antenna is a demanding process, which affects your time to market and product development costs. Radientum’s Antenna Design turn-key service fits into your product development process – so that you can concentrate on developing a superior device while we bring in our world-class antenna design expertise, equipment, and facilities.

Feasibility study

You have a vision of a wireless product. So, you know how it should look like, what materials will be used, what’s the desired connectivity experience, and more. The first task is to find out how these requirements affect antenna design – and is your vision realistic. Feasibility Study enables you to do just that!

The feasibility study is the first step of the antenna design journey. It verifies that your product plan and connectivity requirements are feasible from the antenna design perspective, and identifies the wireless protocols (e.g., LTE, NFC, Bluetooth) that can be used to achieve the desired RF performance. With our simulation-driven process, we can provide you with a comprehensive feasibility study faster and more cost-efficiently.

A feasibility study is your reality check before committing to product development and advancing to the next design phase – Antenna Concepting.

Antenna Consultancy

Antenna concepting

How to implement an antenna that delivers optimal wireless connectivity for the user? Can you use an off-the-shelf antenna, or is custom antenna required? How can your product meet the regulations and official certifications? How to optimize the RF performance while reducing the development time and costs? All this, and more, is defined in Antenna Concepting.

Antenna Concepting describes the best-practice antenna design approach for your product – a design framework. The outcome report includes aspects such as the antenna structure, components to be used and their placements, and interfaces, wireless technology including band variants, manufacturing method, and optimal implementation model: an off-the-shelf or custom-made antenna. It also identifies possible mechanical requirements imposed on the product and provides a simulation-based performance forecast.

Properly conducted Antenna Concepting reduces your workload and avoids costly and time-consuming amendments later in the antenna design – when each change can have complex ramifications for several other branches of the product development.

Detailed design

In Antenna Concepting, you have laid out a rough design framework for the antenna. The next step is to select the design approach with the highest potential and commence with the actual, detailed Antenna Design!

The detailed Antenna Design phase involves antenna hardware, structure, matching elements, grounding, printed circuit board, interfaces between the antenna and other components, and all the other critical design items. Optionally, the EMC, EMI, and SIPI tests can be carried out, as well as interference elimination. The detailed design takes into account the regulations, certifications, operator requirements, and, if needed, planning for the second source of manufacturing.

With the detailed design report, which includes the performance report, and detailed CAD drawings, you can now place the order for the prototypes!

This is the last design phase before the prototype is manufactured. That’s why a careful, professional, and simulation-aided antenna design is critical – testing and amendments are much more expensive and time-consuming with the prototype.

Prototype verification

In Prototype Verification, the RF performance is measured with a physical prototype for the first time during the process. On the other hand, this is the final step before entering the mass-production phase, which is why it is critical – the RF performance can still be optimized easily using the prototype. After you have manufactured products, it is much more difficult and costly to make modifications – and, they compromise the overall product quality, or in the worst case, produced batches will have to be scrapped.

Prototype Verification can be started with a non-functional prototype. Software, for instance, is not needed. Over-the-air (OTA) measurements such as TRP and TIS can be carried out optionally.

The purpose of the prototype verification is to optimize and fine-tune the antenna performance and make sure the product fulfills the regulations, certifications, and operator requirements. The matching components are tuned with the final settings. As a result, you receive the final verification report with an updated design and CAD drawings. You are ready for manufacturing!

Antenna Testing & Tuning
RELATED: How is your antenna doing?

Antenna pre-certification

Once you have received the manufactured products, it is time for the final, official certification tests.

At this point, we recommend you conduct Antenna Pre-certification tests. This is to verify that the particular unit is fully functional, before sending it to the official certification tests. With Antenna Pre-certification, you can avoid failing the official test due to a malfunctioning or broken device.

Manufacturing support

When the official certification tests are passed, you are finally ready to enter manufacturing! How can Radientum help you here? We can support you in many activities related to the antenna to smoothen your manufacturing process – e.g., introduce valuable and trusted partners, evaluate and validate production line testing, or verify the second source.
