Document Type and Number:
WIPO Patent Application WO/2019/049647
Kind Code:
The purpose of the present invention is to improve communication performance. A substrate (2) has a conductor part (23) to which constant potential is applied. A first communication part (3) transmits a first signal in a first frequency band. A second communication part (4) performs transmission of a second signal in a second frequency band which has higher frequencies than the first frequency band and which at least some of harmonics of the first signal overlap and/or reception of a third signal in the second frequency band. A first end (51) and a second end (52) of an electrically conductive wire (5) are connected to the conductor part (23). The second communication part (4) has at least one of a transmission filter that allows passage of the second signal, a reception filter that allows passage of the third signal, and a low noise amplifier that amplifies the third signal. The electrically conductive wire (5) is located between a power amplifier in the first communication part (3) and at least one of the transmission filter, the reception filter and the low noise amplifier in the second communication part (4).
