Case Study: Synapse Increases Antenna Range by 5X
Objective
• Deliver reliable wireless connection without creating health hazard
• Optimize power consumption, size, aspect ratio, and weight
Results
• Increased antenna range by 5X
• Reduced design cycle by 25%
ANSYS Solution: Antenna Design and Placement
Synapse uses ANSYS HFSS and the ANSYS human body model to evaluate performance of various antenna designs by modeling the complete system, including the wireless device and antenna and their interactions with the human body
