PROBLEM TO BE SOLVED: To solve the problem of electrolytic coupling that prevents required antenna characteristics from being maintained when a plurality of independently functioning antennas are arranged adjacently. SOLUTION: A plurality of the single antennas 2 and 3 functioning as the independent antennas are arranged adjacently. Side-face grounding electrodes 12 at ground potential are mounted on the side faces of the opposed base bodies 4 and 5 of the single antenna 2 and the single antenna 3. According to the constitution, the extent of an electric field in the direction of the adjacent single antennas 2 and 3 is inhibited, and electrolytic coupling between the adjacent single antennas 2 and 3 is weakened.
