Antennas are sensitive to their surroundings. Thus, when there’s an antenna on the PCB, the layout for the design should take the requirements of the antenna into account, as this can make a huge difference in the wireless performance of the device. Care should be taken when integrating an antenna into a new design. Even the material, layer count, and layer thicknesses of the PCB can affect an antenna’s performance. This article discusses some basic design concepts that will help a designer derive great performance from an antenna.
