PROBLEM TO BE SOLVED: To provide an antenna which is set up to a rear glass of a vehicle provided with a defogger and uses a loop antenna with a very few performance deterioration. SOLUTION: As for a structure of the antenna, the antenna 10 is formed by connecting feeding points of two loop antennas having an optional shape by a first linear conductor 75 and a second linear conductor 76, a first feeding terminal 91 and a second feeding terminal 92 to feed to the first and second linear conductors 75 and 76 each are set outside an antenna conductor at intervals of a prescribed distance, a way of the second linear conductor 76 is divided at intervals of the prescribed distance, the first feeding terminal 91 is connected to the way of the first linear conductor 75 passing through a space 70 divided by a first drawing line 77, and the second feeding terminal 92 is arranged adjoining the first feeding terminal 91 and is connected to a dividing point of the second linear conductor 76 by second and third drawing lines 78 and 79 holding the first drawing line 77.
