WebThe proposed beam-switchable antenna is designed with the Yagi-Uda method at 2.4 GHz. Whereas a conventional ES-PAR antenna has a single parasitic element for each beam di-rection, the proposed antenna has additional parasitic antenna elements to achieve higher directivity. The Yagi-Uda array an- A Yagi–Uda antenna, or simply Yagi antenna, is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array; these elements are most often metal rods acting as half-wave dipoles. Yagi–Uda antennas consist of a single driven element connected to a radio transmitter and/or receiver through a transmission line, and additional "passive radiators" wi…
WebThe antenna radiates radio waves in a beam toward the right. In an antenna array made of multiple conductive elements (typically metal rods), a driven element or active element is … The multiple other elements are parasitic, which reflect and direct the radiated signal into a single direction, hence a beam antenna. Yagi–Udas are used for rooftop television antennas, point-to-point communication links, and long distance shortwave communication using skywave ("skip") reflection from the … See more In radio systems, many different antenna types are used whose properties are especially crafted for particular applications.
