PCB Antenna Design Works Hand-In-Hand with Simulation Software

When designing antennas for PCBs, the first step is to establish the frequency ranges, including the center frequency and bandwidth. Software tools can assist in determining these parameters and estimating the necessary power levels. Following this, antenna sizing is crucial and should be based on the layer stack of the PCB, a process greatly facilitated by design software that can model different configurations and constraints.

The selection of materials for the PCB stack-up is integral to the design. While the entire board doesn't require uniform material, surface layers often utilize specialized materials. For instance, in a mixed-signal PCB carrying digital, RF, and analog signals, the choice of material for each layer is essential. Software can help in material selection, ensuring compatibility with cores and prepregs that are more general-purpose and robust.

In terms of antenna design, employing multiple patch antennas can enhance power and sensitivity. These antennas are arranged in an array, spaced at half or quarter wavelengths, depending on their orientation. The orientation is key to boosting far-field signal strength or sensitivity. Software plays a pivotal role here, aiding in calculating the precise placement and spacing of these arrays, and simulating their performance to optimize signal strength.
