Abstract

PURPOSE:To reduce the number of components to be employed to attain light weight and to reduce the cost by arranging two dipole antennas whose frequency band differs from each other on a same dielectric board to be arranged orthogonal to each other. CONSTITUTION:A signal whose frequency is f1 sent from a signal generator is led through a feeder 4 being parallel wires and fed to thin film conductors 2a, 2b of a dipole antenna 2 formed on a dielectric board 1, the length of the dipole antenna 2 is selected to be active on the frequency f1 and a radio signal whose frequency is f1 is radiated from the dipole antenna 2. Since two dipole antennas 2,3 whose frequency band differs from each other are formed on the same dielectric board, a problem of interference is considered, the two dipole antennas 2, 3 are arranged orthogonal to each other and they are excited by an orthogonal polarized wave and the magnitude of the interference is sufficiently decreased.
