Agilent upgrades antenna modeling system with hearing-aid compatibility

The new capability will help designers to meet recent U.S. requirements to have 50 percent of new phones hearing-aid compatible with the IEEE American National Standard Methods of Measurement of Compatibility (ANSI C63.19-2006).

Development of the AMDS HAC functionality was a joint effort of Agilent's EEsof EDA R&D team and the development team at Remcom Inc.

AMDS imports, meshes and simulates an entire wireless device, together with its surrounding real-world environment, to analyze compliance standards such as HAC, SAR (Specific Absorption Rate), and antenna diversity and MIMO (Multiple-Input, Multiple Output).

Simulating the device with AMDS can reduce design cycle time significantly, eliminating up to 75 percent of the typical modeling and setup time that is required by other types of EM simulators.

AMDS is a full wave, 3-D, dedicated design, modeling and verification tool for antenna systems and placement. The new release, version 2007.4, allows users to evaluate hearing-aid compatibility (HAC) between wireless communication devices and hearing aids.

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.

The Agilent AMDS is available now with prices starting at approximately $50,000.
