As a result of increased connectivity, the need for compact mobile communication devices has grown considerably. This requires that the size of the antennas mounted on these devices need to be miniaturized. This has given rise to devices having internal antennas. Due to their small size, the antennas utilized in these devices should have high gain and bandwidth. This makes the Yagi-Uda a good choice for this purpose. A Yagi-Uda antenna consist of a dipole arranged with some parasitic elements.
