Yagi-Uda antenna is a practical radiator in the HF (3-30MHz), VHF (30-300MHz) and UHF (300-3000MHz). Yagi - Uda antenna using microstrip circuits is a very demanding structure in the 4G cellular applications. Using microstrip circuits, size of Yagi-Uda antenna can be designed in mm dimension as compared to the Yagi-Uda design formed from large conducting wires. Microstrip circuit Yagi-Uda antennas are quite common in practice because they are lightweight, simple to build, low-cost and provide moderately desirable characteristics (including a unidirectional beam) for many applications.
