Microstrip is a type of electrical transmission line used to guide microwave signals. It consists of a thin conducting strip separated from a ground plane by a dielectric material. This structure allows for efficient signal transmission with minimal loss, making it ideal for high-frequency applications. Microstrip is commonly used in various devices, including antennas, filters, and amplifiers. Its compact design enables integration into printed circuit boards (PCBs), which are widely used in electronics. The simplicity of its construction and the ability to fabricate it using standard PCB techniques contribute to its popularity in modern communication systems.
