High-frequency RF and microwave circuits require a different approach in the design process than a standard printed circuit board. The AWR product line is taylored for these applications and works in conjunction with the OrCAD and Allegro design flow for PCB.
Antennas, waveguids and filters are captured in a special schematic entry and layout canvas which are both very tightly integrated. The shape of the layout (metal on PCB) defines the function of the structures themselves. To capture the behaviour of the circuit, the layout need to be extracted by a field solver with all the parasitic influences of the structures and its surrounding metal. After extraction creates an electrical model of the structure, the behaviour of layout vs frequency can be simulated.
The AWR products are used for radio frequency (RF), microwave and high frequency analog circuits and system design. Typical applications include mobile, navigation, and satellite communications systems, antennas of various kinds (WLAN-IoT, 5G, WiFi-6, ...), radar systems and RF power devices.
To streamline high frequency electronic design the solution offers electromagnetic (2.5D and full 3D), linear and non-linear solvers (both frequency and time domain) as well as layout capabilities all within a single environment to improve the design efficiency. Different applications require different level of analysis, so AWR offers with AXIEM a method of moments (MoM) planar solver as well with Analyst a 3D FEM EM simulation and analysis simulator. But also interfaces to other simulators like Spectre, Clarity or others depending on the engineering need.
Proper design of RF antennas on PCBs determines the quality of the antenna. Various parameters describe the quality of antennas.
