Abstract:
1. An antenna combining module that performs conversion between a common antenna signal and a plurality of individual signals, comprising: a plurality of individual signal lines through which respective individual signals pass; an antenna common line through which the common antenna signal passes; a ground line that is at ground potential; and an inductance element that grounds the antenna common line; wherein the individual signal lines, the antenna common line and the inductance element are defined by wiring electrodes provided on a substrate surface and/or a substrate interface and by via electrodes located inside a substrate; one end of the inductance element is connected to a grounding mounting electrode that is located on one main surface of the substrate and the inductance element is arranged so as to wrap around a via electrode included in the antenna common line; and the ground line is arranged between the individual signal lines and the antenna common line and the inductance element.
