YAGI-UDA Antennas for AMPS/GSM 900-1800-1900 MHz/UMTS/PCN/DCS/3G/HSDPA

Yagi-Uda Antenna is commonly known simply as a Yagi antenna or Yagi. It is a directional antenna system consisting of an array of a dipole and additional closely coupled parasitic elements. This antenna has the directionality that a single dipole lacks. Directional antennas, such as the Yagi-Uda, are also commonly referred to as beam antennas or high-gain antennas.
