Communications
5G and emerging 6G technologies bring unprecedented data rates and device density, and the antenna systems enabling them are growing in both number and complexity. The average smartphone now contains 4 to 8 antennas, compared to 2 to 3 in 2018, and 5G devices require 30 to 50 percent more antenna components than their 4G predecessors.
The engineering challenge
The hard problems sit at the system level. Electrically small, multi-band antennas must be packed into devices without degrading one another. Massive MIMO and beamforming arrays depend on element-to-element coupling that has to be modeled together, not element by element. And the move to millimeter-wave, spanning roughly 24 to 100 GHz, makes accurate modeling both more important and more computationally demanding.
As these systems grow, legacy tools either run out of memory and force you to simplify the model, or take so long that simulation becomes the schedule bottleneck.
Dense multi-antenna devices create coupling and compatibility problems that isolated models miss
Massive MIMO arrays depend on element-to-element interactions that must be solved together
mmWave frequencies raise the computational cost of accurate modeling substantially
Simplifying the model to fit the tool undermines confidence in the result
The Nullspace solution
Nullspace EM covers the full spectrum of communications antenna design, from electrically small handset antennas to large infrastructure arrays. It computes gain patterns, multi-antenna coupling for EM compatibility, and passive and active S-parameters, all central to getting these systems right the first time.
The same rigorous solver scales from a single element to a complete array, and Python-based scripting integrates simulation into your design toolchain.
Full-device analysis captures the coupling and compatibility effects between co-located antennas
Arrays are solved with all element-to-element coupling preserved, with no unit-cell shortcuts
Full-wave accuracy holds across frequency, from sub-6 GHz through millimeter-wave
The full problem runs at full fidelity, so no confidence is traded away to make it fit
