Antenna Design & Modeling Software

Understanding the factors affecting antenna performance when installed on real-world platforms is crucial to a sustainable design process.

Smarter Antenna Design and  Placement Simulation

Antennas are virtually everywhere. From commercial applications such as smartphones, RFID tags, and wireless printers, to defense applications such as phased array antennas for aircraft radar systems or autonomous vehicles, to integrated ground-based communication systems. 

Electromagnetic simulation of antenna design and its interaction with the entire system allows designers to evaluate “what if” real life scenarios.

Better, Faster Communication Design with Antenna Simulation

From increasingly powerful consumer mobile devices to the most advanced design challenges driving manufacturing and critical applications, the future of technology asks more from antennas than ever before. No matter the sector, simulation is the solution to execute high-performance antenna and platform designs with minimal wasted effort and money. 

5g antennas


Antenna beamforming and beam steering in 5G are key to improve the capacity and data rates. Massive MIMO requires phased array antennas to optimize the link and ensure targeted coverage.

Autonomy car


Ansys tools are ideal for designing and simulating antennas, antenna-to-antenna coupling and environmental effects on signal propagation. HFSS SBR+, a powerful, large scale electromagnetic field solver, can simulate automotive radar range-doppler returns of complex driving scenarios. 

IoT video


With our advanced technologies for 3-D simulation, customers can assemble different IoT components into complete virtual prototypes of software-controlled, multi-domain systems.
