Full Wave Matching Circuit Optimization Shortens Design Iterations

Full Wave Matching Circuit Optimization Shortens Design Iterations

Full wave matching circuit optimization (FW-MCO) is a new technology that combines full wave, 3D EM simulation with circuit optimization into a novel approach for solving an age-old RF problem: determining which component values provide the desired match for a given matching network layout. This article describes the design process using the design of a matching circuit for a GPS-Bluetooth antenna.

Overview of XFdtd's Circuit Element Optimizer

Overview of XFdtd's Circuit Element Optimizer

XF’s Circuit Element Optimizer utilizes full wave analysis to select the component values for a given printed circuit board (PCB) layout. The tool allows design engineers to optimize matching circuit lumped element values directly in the EM layout where the coupling from multiple antennas and the ground return current paths are taken into account. This whitepaper gives an overview of how the Circuit Element Optimizer works and the benefits it provides.

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.
