Synthesize, optimize, and integrate antennas for next-generation sensors, radars, and communications systems

Radiate Further, Faster

RF designers of today's 5G and IoT smart devices need specialized simulation and optimization technology to develop small-size, embedded antennas with high gain and single-, multi-, and wideband frequency range. AWR software helps engineers design, optimize, and integrate antennas/arrays, providing powerful EM technologies to simulate antenna metrics such as gain, return loss, radiation efficiency, and currents, and to visualize 2D/3D far-field antenna patterns. Furthermore, the AntSyn antenna synthesis tool jumpstarts designs by synthesizing physical antennas based upon user-specified performance requirements.

Solution Highlights

Design Starts

In order to convert bound circuit fields into propagating electromagnetic (EM) waves and radiate those fields into signals for processing within the receiver, antenna design focuses on developing a structure that emits and/or receives EM waves as efficiently as possible for a specific frequency range and geometric form factor. With the development of high-performance cloud computing, powerful EM analysis, and advanced optimization techniques, engineers can now reliably use antenna synthesis software to generate physical designs from electrical requirements.


The size of the antenna compared to the wavelength at the frequency of operation is an important determinant of the computational method used for EM analysis of antenna performance. Specialized codes for electrically-large antennas rely on high-frequency approximations and EM simulators must also make the boundary box containing the antenna invisible to the fields radiating from the structure. The appropriate simulation technology is also dependent upon the geometry of the antenna, such as planar (patch) versus arbitrary 3D (horn, parabolic).


Parameterization enables designers to readily analyze and optimize planar and fully 3D structures over a user-specified range of property values. Combining this capability with EM analysis supports highly-accurate performance and yield optimization that addresses manufacturing tolerances affecting performance factors such as efficiency and return loss. In addition, parallel computer processing, in which the problem is distributed to more than one computer, allows antenna designers to explore more design options in less time.

Impedance Matching and Integration

RF circuit simulation and network synthesis tools help antenna designers develop impedance-matching circuits that ensure maximum delivery of power to the antenna from the front-end circuitry. An RF-aware circuit and/or system simulator is critical to investigating the antenna performance in the context of the entire wireless device.

Associated Products

AWR Design Environment

The AWR Design Environment platform provides a single, complete design environment that seamlessly integrates simulation and design technology and manages the circuit/system/EM components within a project, supporting schematic design entry and fully-synchronized physical design and layout to define an antenna design and related RF circuitry.


The AXIEM 3D proprietary full-wave planar EM simulator is based on method-of-moments (MoM) fast solver technology that readily analyzes planar antennas and arrays.  AXIEM software extracts S-parameters for voltage standing-wave ratio (VSWR), return loss, and radiation patterns, and provides visualization of EM fields and currents.


The Analyst™ simulator enables designers to model arbitrary 3D structures such as horn and helix antennas with integrated 3D finite-element method (FEM) EM analysis to extract S-parameters for voltage standing-wave ratio (VSWR), return loss, and radiation patterns, and provides visualization of EM fields and currents.  


The AntSyn™ design, synthesis, and optimization tool enables antenna designers to input their engineering requirements and produce antenna designs as outputs to address the growing demand for wireless connectivity optimized for system performance, cost, and size. 

Microwave Office

Microwave Office circuit design software helps designers develop impedance-matching networks and antenna feed structures with RF/microwave linear circuit simulation, distributed transmission lines, and vendor component libraries, as well as design aids such a network synthesis (optional), optimization, and tuning.

Visual System Simulator

Visual System Simulator™ (VSS) system design software, together with the phased-array generator wizard, enables designers to quickly configure planar phased-array or MIMO-array systems, interactively modify designs to achieve the desired behavior, and then generate system diagrams and/or circuit schematics and EM structures for further, more rigorous analysis. VSS software supports interactive specification of the layout, feed network settings, element antenna and RF link settings, gain tapers, and element failures.


Network synthesis automatically creates two-port, impedance-matching networks for single- and multi-band antennas using proprietary evolutionary EM optimization.

The radar library within the phased-array generator wizard enables rapid configuration of phased-array antenna systems, supporting feed network development, gain tapering, and simulation of MIMO and beam-forming arrays.
