MULTIBAND AMATEUR RADIO ANTENNA DESIGN

Amateur radio is the field of communication that can bring enjoyable for someone beside it can be used for emergency communication and military radio system. Normally, amateur radio running in the range of frequency from 3-30 MHz. The one of the main components used in amateur radio system is the antenna as transmission medium to transmit the signal. This report is highlight the simulation design for three, five and seven elements of half lambda Yagi antenna by using EZNEC Demo v.5.0 software while the substrate prototype is fabricated using some aluminums rod, RG 58 coaxial cable, FT-817ND transceiver and RF field strength meter. The report will discuss the result from the EZNEC simulation part with the actual prototype for three, five and seven elements Yagi in term of radiation pattern, maximum gain and Front-to-back ratio.
