Agilent Technologies Inc. (NYSE:A) recently released its latest Antenna Modeling Design System (AMDS). The full-wave 3-D electromagnetic (EM) modeling and simulation software contains a scripting feature for performance optimization and automation of complex designs such as patch array antennas, allowing designers to fine tune antennas for the best performance within electronic devices, such as handheld wireless cell phones. The Agilent AMDS is available now with prices starting at approximately $50,000.
AMDS is a full-wave, 3-D EM design, modeling and verification tool dedicated to antenna and antenna systems design. It meshes, simulates and optimizes 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 devices with AMDS can reduce design cycle time by up to 75 percent compared with that required by other types of EM simulators available today.
The new scripting capability in this fifth release of AMDS allows designers to write their own programs to automate element placement and incorporate mathematical functions to perform virtually any analysis on the antenna design before it is integrated into the complete mobile wireless device. Designers also can use equations to define the geometry of complex antennas (such as those with fractal and conformal surfaces) to optimize performance.
