Abstract
Provided is a loop antenna which can contribute to an increase of an area of a radio system using a magnetic field. The loop antenna includes a main loopwhich is an open loop connected to a signal sourceor a reception circuit; and an amplification loopwhich is a closed loop having the same shape as the main loop. The main loopand the amplification loopare arranged on a same surface of a flat substrate formed of an insulator. A first capacitance is connected to the main loop, and a second capacitance is connected to the amplification loop.
