Abstract

PURPOSE:To enable to form the Yagi-antenna high in the gain, of miniature size and light in weight, by using the shorted antenna elements having folded shape and distributed inductance. CONSTITUTION:One of dipole antennas as waveguide, radiator and reflector is constituted as shown in figure, and the shorted antenna elements 15, 15' having distributed inductance are employed with metal foil low in electric resistance such as copper, and the specified points are formed with the pattern folded at respective direction and angle for a required number. With this constitution, in the elements 15, 15', the distributed inductance is operated to be turned out to be equivalent to the coil canceling the reactance added to the conventional elements, making unnecessary the lumped constant coil. Since the conductor having broad surface area such as foil can be used, the loss is small and small size can be realized.
