PROBLEM TO BE SOLVED: To provide a broadband antenna including both electric and magnetic radiators for achieving high-efficiency and low-loss broadband operations. SOLUTION: A slot antenna (magnetic radiator) 210 is arranged on a conductive first plane (ground plane 220), and a monopole antenna (electric radiator) 250 is arranged on a perpendicular plane perpendicular to the ground plane 220. The monopole antenna 250 is coupled to one end of a feeder body 240. The slot antenna 210 and the monopole antenna 250 are coupled so that a PxM radiation pattern can be formed in the range of an operating frequency, and a conventional lossy element (resistive load) is prevented from being coupled between the feeder body 240 and the ground plane 220, and a reactance load 260 is installed instead.
