<p>PURPOSE: A portable terminal is provided to reduce mutual interference between transmission-reception antennas by arranging a mode converter and a connection line to a MIMO antenna. CONSTITUTION: A portable terminal includes a first antenna(400), a second antenna(405), a connection line(410), and a mode converter(415). The connection line connects the first antenna and the second antenna. The mode converter includes a first and a second port. The first and the second port are connected to an impedance matching circuit. The mode converter respectively transmits a first and a second electrical signal to the first and the second antenna. The first and the second electrical signal are orthogonal each other.</p> |
