Abstract

PURPOSE:To obtain a simple antenna with a low cost, which features the wide band properties including the FM, VHF and others by attaching the 150OMEGA-feeder featuring the length of about half wavelength to the half-wave folded antenna element made of the material of the thin wire. CONSTITUTION:Antenna 5 is formed by connecting parallel-type 150OMEGA-feeder 7 of about half wavelength to half-wave folded antenna element 6. In such constitution, the conductor of 7/0.18mm is used to feeder 7 to secure a low cost. At the same time, the easy-to-split parallel-type 150OMEGA-feeder featuring the length of about one wavelength is used as the material to form antenna 6. In other words, this feeder is split at its half into two pieces 7b and 7c leaving 7a equivalent to about 1/2 half wavelength, and then folded at about the middle point. Then tip conductors 7d and 7e are soldered together to secure the short circuit. Also the terminal process is given to the other end 7f for connection of the receiver.
