Abstract

PURPOSE:To easily confirm a directional state, determined by combining dipole antennas, by displaying the specificity of a signal that controls and sets the direction by converting the signal into a display signal corresponding to the direction by a simple signal converting method. CONSTITUTION:Antenna part 45 is provided with antenna element constitution part 46, switching control part 47 that changing over combinations of dipole antennas and signal composite devices in constitution part 46, and switching signal generation part 48 that supplies control signals to control part 47. Switching setter 50 is connected which exercises desired switching control by supplying switching setting singals to generation part 48. Then, switching tuning control signals switched by control part 47 are supplied to constitution part 46 and also to voltage comparison part 51, which compares voltage levels of respective switching tuning control signals as to every required signal to output logic signal ''1'' or ''0'' according to the voltage level comparing way. This signal ''1'' or ''0'' is converted by logic signal converter 52 into a display signal that corresponds to the indicated direction and it is displayed by display device 54.
