WiFi antennas in laptops are typically integrated within the screen assembly, often running around the perimeter of the screen to maximize signal reception. This design helps in leveraging the vertical placement for better signal strength and is a common practice across most laptop manufacturers. Antennas are rarely found around the touchpad as it is an area of frequent contact and does not provide enough space for optimal placement, nor they are installed near speakers as electromagnetic interference can impact signal quality. They are also not located near the motherboard's I/O to prevent interference with other signals and preserve space for other components.
