Laird Technologies, Inc. has deployed advanced 3D simulation tool as an aid in the design of complex electronic devices, including advanced antenna systems. Utilizing Ansoft’s HFSS Distributed Solve (DSO) design tool, designers at Laird Technologies can now synthesize entirely new designs and evaluate advanced design concepts that were previously too complex to simulate, stated the company..

According to Blaine Bateman, Laird Technologies’ vice president of marketing, the increasing popularity of smart phone applications has resulted in mobile telephones with multiple wireless interfaces and antennas concentrated in a small handheld device. Multiple antennas are now required to support emerging standards that use multiple input, multiple output (MIMO) technology.

“The ability to simulate effects of multiple antennas coupled to other subsystems in the device is critical for next generation protocols supporting live video, high data rate transmission, interactive web surfing, and other wireless Internet capabilities,” Bateman said. “Using the latest capabilities in HFSS, our designers can now simulate the antenna system in the presence of the entire phone including the effects of shielding, speakers, integrated digital cameras, and the multiple bands required to support GSM, Bluetooth, GPS, wireless networking, and future wireless standards.”

“Our DSO design tool represents the next evolution in high-performance design improvements for solving very large problems in 3D mesh-making, solution capacity, and memory management”, said Zoltan Cendes, Ansoft’s founder, CTO, and chairman of the board.
