Award Winning Technology Author Bill Schweber Writes:
Designers of handheld and portable wireless products such as smartphones and wearables rely on tiny chip, patch and trace antennas that can be placed within the device. While these miniature devices solve the problem of bringing multiband antenna arrays to small form factor systems, they also introduce issues related to reduced radiation efficiency, impedance matching, and interaction with nearby objects and bodies.
To address these problems, designers are being armed with new design and circuit techniques to make these antennas more than just a standalone component. Instead, they are becoming part of a dynamic antenna subsystem that mitigates many of these design challenges. This shift in design requires extensive simulation and analysis, which is being addressed by constantly improving field solver software. http://bit.ly/2s6ZqEw
