Time-Saving Technologies to Simulate and Tune Conformal Antennas for Modern Mobile Devices

Time-Saving Technologies to Simulate and Tune Conformal Antennas for Modern Mobile Devices

The bottlenecks for simulation tools used for antenna design are typically in two areas: project setup and simulation speed.  By reducing the time spent in these two areas, RF engineers have more time to design their antennas.  Remcom’s XFdtd reduces these bottlenecks in several ways, including parameterization, scripting, advanced meshing techniques, and GPU implementation of the computational algorithm.

 

Bandwidth, SAR, and Efficiency of Internal Mobile Phone Antennas

Bandwidth, SAR, and Efficiency of Internal Mobile Phone Antennas

This paper presents a thorough investigation into the effects of several phone chassis-related parameters—length,width, thickness, and distance between the head and phone—on the bandwidth, efficiency, and specific absorption rate (SAR) characteristics of internal mobile phone antennas. The studied antenna-chassis combinations are located beside an anatomical head model in a position of actual handset use.
