  • Publication number: 20190109377
    Abstract: An object of the present invention is to vary the directivity of an antenna (100a) while reducing the signal loss by switching circuits (5a-5d) in a splitter circuit. The switching circuits (5a-5d) in the splitter circuit connect or disconnect n (n is an integer of 2 or more) second lines (12a) connected in parallel with a first line (10a) to/from output terminals (7) connected to n antenna elements (8) having different directivities of signals. If m (m is an integer ranging from 1 to n?1) switching circuits (5b, 5d) arbitrarily selected from the n switching circuits (5a-5d) are switched to on-states, the characteristic impedance of each of the n second lines (12a) is set to a product between the characteristic impedance of the first line (10a) and the number m of switching circuits (5b and 5d) switched to on-states.
