👉 Semiband is a type of microstrip strip with a diameter of 2.5 to 4 inches (6.3 to 10 cm) that is used in microwave and radio frequency (RF) applications for electromagnetic wave transmission. Semibands are also known as "microring" or "microring strips." They are particularly useful for high-frequency communication systems, such as those used in radar and satellite communications, where the bandwidth of the transmitted signal must be limited to a specific range
