EXPERIMENT NO: 03   AIM: Design of Yagi Uda Antenna Using HFSS Software. SOFTWARE USED: ANSYS HFSS 15.0.3 THEORY: A  Yagi–Uda antenna, commonly known as a  Yagi antenna, is a  directional antenna  consisting of multiple parallel elements in a line, usually  half-wave dipoles  made of metal rods.  Yagi–Uda antennas consist of a single  driven element  connected to the  transmitter  or  receiver  with a  transmission line, and additional "parasitic elements" which are not connected to the transmitter or receiver: a so-called re ector and one or more directors.  It was invented in 1926 by  Shintaro Uda  of Tohoku Imperial University,  Japan, and (with a lesser role played by his colleague) Hidetsugu Yagi. The re ector element is slightly longer than the driven dipole, whereas the directors are a little shorter. This design

achieves

a

very

substantial

increase

in

the

antenna's directionality and gain compared to a simple dipole.

Also called a "beam antenna", or "parasitic array", the Yagi is very widely used as a high-gain antenna on the HF, VHF and UHFbands.  (source: Wikipedia)
