PROBLEM TO BE SOLVED: To realize low power consumption and simplification of a system in the inside of an IC by synthesizing antenna output of three directions in the outside of the IC. SOLUTION: The receiver is provided with a plurality of antennas according to each of the directions capable of receiving input signals from a plurality of directions. In this receiver, output signals from the respective antennas which have received the input signals from the plurality of directions are synthesized outside of the IC, antenna coils Lx, Ly and Lz provided so as to correspond to the plurality of directions are connected in series in order to transmit the signals to the following circuit (amplifier circuit 2) in the inside of the IC 1, and a capacitor C is connected to the coils Lx, Ly and Lz in parallel.
