PROBLEM TO BE SOLVED: To provide an antenna assembly which is simple in feed structure and easy to adjust impedance at a high gain in a broad band. SOLUTION: Three loop elements 31-1 to 31-3, 37-1 to 37-3 are connected in series to form loop antennas 35, 36, and each loop antenna 35, 36 is fed in parallel to simplify the feed structure, obtain a high gain and broad band structure, and facilitate adjusting the impedance.
