Abstract
A multi-antenna module includes, on or in the dielectric substrate, a first radiation element, a second radiation element that operates at a frequency band lower than that of the first radiation element, and a ground plane. A first feed line and a second feed line are provided on or in the dielectric substrate. A first switch element switches between a first state in which a signal is supplied to the second radiation element and a second state including at least one of a state in which the second radiation element is connected to the ground plane with terminal impedance interposed therebetween, a state in which the second radiation element is in a floating state with respect to the second feed line and the ground plane, and a state in which the second radiation element is short-circuited to the ground plane.
