Traditional communication systems have relied on single antenna designs or switching between different antennas within the system for maximum throughput (diversity). 5G requires this in addition to the use of arrays to perform beam steering.
XFdtd is keeping pace with 5G design requirements by providing an Array Analysis capability. The full wave solver in XF is used to compute the S-Parameters, efficiencies and far field for each of the elements in all the arrays of a device. The Array Analysis tool then uses that information to optimize the phases of the feeds for each element over a set of desired beam angles. A cumulative distribution function (CDF) plot is then generated for one or more arrays to provide a total metric of the performance of the device.
