AMDS 3D EM v2007.4

Agilent Technologies Inc.'s new Antenna Modeling Design System (AMDS) now contains new capabilities to verify that handheld wireless devices are equipped with hearing-aid compatibility. This is the second release of AMDS, Agilent's EM simulation tool dedicated to modeling and verifying antennas and antenna systems. The software helps to meet performance specifications and reduce design risks in handheld wireless devices.

AMDS is a 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, according to the IEEE American National Standard Methods of Measurement of Compatibility (ANSI C63.19-2006). The standard establishes categories of compatible hearing aids and wireless devices.

"By February 2008, all wireless carriers in the U.S. must ensure that 50 percent of their phones are hearing-aid compatible," said Erwin De Baetselier, product marketing manager with Agilent's EEsof EDA division. "Today, we are leading the industry by offering HAC compatibility tests in our EM simulation environment, ensuring that designers of wireless devices will be able to meet these important and rigorous specifications."

Development of the AMDS HAC functionality was accomplished through the joint efforts of Agilent's Ees of 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 multiple-input, multiple output (MIMO). 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.

The AMDS 3D EM feature set includes efficient importation of CAD data from product designers, reducing or eliminating EM design iterations as well as verification of antenna compliance with legal and operational standards such as SAR, HAC, over-the-air performance and MIMO. It also offers 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 tool is available now with prices starting at $50,000.

Agilent is participating at the 7th Embedded Systems Conference-Taiwan (ESC-Taiwan) and the 15th EDA & Test-Taiwan Conference & Exhibition (EDA&T-Taiwan on August 23-24 at the Taipei International Convention Center.
