Growth is driven by consumers replacing existing devices with new ones that offer added functions and longer battery life in smaller stylish housings. Manufacturers are competing to offer these at lower prices by outsourcing and modular designs. However, this business model impacts R&D"s ability to ensure consistent device quality and performance.

Wireless appliance designs face the challenges of fitting multi-band antennas into small stylish housings to entice consumers and yet have to comply with regulatory, operator and end-user demands for radiation safety and performance quality.

AMDS is the only 3D-EM antenna design tool specifically developed to enable antenna and product industrial designers to overcome these challenges.

It cuts subsequent modeling and simulation setup by more than 70% compared to some of its competitors, making simulation the evident choice for the antenna designer.

It efficiently imports, meshes and simulates the entire wireless appliance including its surrounding real-world environment to analyze compliance standards such as SAR (Specific Absorption Rate), HAC (Hearing Aid Compatibility), and MIMO (Multiple-Input, Multiple Output) antenna diversity.

It cuts design cycle time and risks before going into slow and expensive physical testing.

The AMDS 3-D EM feature set includes:

• efficient importation of CAD data from product designers, reducing or eliminating EM design iterations;
• verification of antenna compliance with legal and operational standards such as SAR, HAC, Over-the-Air Performance and MIMO;
• optimization of MIMO performance by analyzing antenna placement and diversity for the entire physical wireless appliance; and
• optimization of device performance by simulating its real-world interaction with the human body.

AMDS enables you to simulate antenna structure and placement within the appliance in the presence of real world proximity effects of the human head and hand to determine parameters such as detuning and sensitivity. This translates to meeting both regulatory and end-user performance requirements before the bottleneck in prototype testing which delays time-to-market.
