摘要： PURPOSE: An antenna is provided to reduce the overall size of a device by reducing the size of the exterior dimensions of the antenna so as to permit the antenna to be assembled into devices that process radio signals and to provide pleasing aesthetics. CONSTITUTION: An antenna(A1) has two antenna elements(E1,E2), and these antenna elements(E1,E2) are electrically connected electrically in series. The antenna elements(E1,E2) are comprised respectively by having an inductance section(1) and a capacitance section(2) that are connected in parallel. A junction point(P1), which is a terminal belonging to the antenna(E1) and represents the end that is not connected to the antenna(E2), is connected to the feed point(3) from which power is supplied to the antenna elements(E1,E2). An impedance matching section is connected as matching circuit externally to the feed point(3) to match the input impedance of the antenna(A1). A junction point(P3), which is a terminal belonging to the antenna(E2) and represents the end that is not connected to the antenna(E1), is connected electrically in series to a frequency adjusting capacitance section(5), and other terminal of the frequency adjusting capacitance section(5) is grounded.
