Antenna and Wave Propagation
Wireless technology is one of the main areas of research in the world of communication systems today and a study of communication systems is incomplete without an understanding of the operation and fabrication of antennas. The main aim of this paper explain basic introduction of antenna and brief explanation of YAGI-UDA antenna .YAGI-UDA antenna mostly use in communication field today in mostly communication system use YAGI - UDA antenna. An antenna is a device for radiating and receiving radio waves. The antenna is the transitional structure between free space and a guiding device.
