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. NI 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.

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.
