PROBLEM TO BE SOLVED: To provide an antenna system comprising a film-like or plate-like conductor pattern usable for a glass antenna, and capable of easily taking impedance matching with a receiver. SOLUTION: The antenna system having a loop antenna element comprising the conductor pattern comprises: an earth means configuring part of the loop of the antenna element; a feeding part for feeding power to the antenna element at one end of the part of the loop of the antenna element configured with the earth means; an the conductor pattern, and includes a parasitic element of a loop shape with a shape and a size similar to those of the antenna element, and the parasitic element is located adjacent to the antenna element at the side provided with the feeding part and the part of the loop is configured of the earth means.
