Patch antennas

Patch antennas are a type of antenna commonly used for wireless communication. They consist of a flat, thin metal sheet—called the patch—mounted over a grounded surface, often separated by an insulating layer. When electrical signals pass through the patch, it radiates electromagnetic waves efficiently in a specific direction. Due to their flat and compact design, patch antennas are ideal for applications like smartphones, Wi-Fi routers, and satellite dishes. They are easy to manufacture, lightweight, and can be integrated into various devices, making them versatile for modern wireless communication.
