Patent abstract
An antenna includes inductance elements that are magnetically coupled together, an LC series resonant circuit that includes one of the inductance elements capacitance elements, and an LC series resonant circuit that includes another of the inductance elements and capacitance elements. The plurality of LC series resonant circuits are used to radiate radio waves and are used as inductances of a matching circuit that matches an impedance when a power supply side is viewed from power supply terminals and a radiation impedance of free space.
