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