Remcom announces a new Circuit Element Optimizerfor XFdtd® Electromagnetic Simulation Software that optimizes matching circuits for several antennas serving multiple bands simultaneously. XFdtd’s Circuit Element Optimizer determines lumped element values based on the following goals: radiation efficiency, system efficiency, and S-parameters. This simplifies the antenna matching workflow because the circuit elements remain in the electromagnetic layout structure during optimization.
Remcom announces a new circuit element optimizer for XFdtd® electromagnetic simulations software that optimizes matching circuits for several antennas serving multiple bands simultaneously. XFdtd’s Circuit Element Optimizer determines lumped element values based on the following goals: radiation efficiency, system efficiency, and S-parameters. This simplifies the antenna matching workflow because the circuit elements remain in the electromagnetic layout structure during optimization.
Jeff Barney, product marketing manager, said, “Traditionally, RF engineers have had to simplify and idealize their matching circuits in schematics that are separated from the EM simulation. This simplification into a lumped element schematic requires perfect grounds and overlooks the coupling and transmission line effects of the interconnect metal and the antennas. XF’s Circuit Element Optimizer is unique because it allows design engineers to optimize the lumped circuit elements directly in the physical matching circuit layout where the EM coupling from multiple antennas and the ground return current paths are taken into account.”
Recent and upcoming technologies in mobile applications, such as inter-band carrier aggregation and new frequency bands, present difficult challenges for antenna designers. Several antennas, each serving multiple bands, may interact with both the device and one another, affecting the antenna match simultaneously. Optimizing in the EM space, the Circuit Element Optimizer addresses these problems. The ability to design devices for multiple mobile carriers is also simplified with support for tunable components, while trade-offs in efficiencies between different scenarios (free space, head and hand, etc.) are realized with the optimizer’s support for different physical configurations.
In addition to inter-band carrier aggregation, the Circuit Element Optimizer can be used for general antenna matching circuit applications, including:
-
Matching circuits for single antenna with single band of operation
-
Matching circuits for single antenna with multiple bands (with or without tunable components)
-
Matching circuits for multiple antennas including MIMO
