To provide an antenna for receiving satellite broadcasting waves which can be installed on one of glass surfaces and has a simple configuration.
The present invention relates to an antenna comprising a linear first element provided with a first feed point of a core wire side and a ground-side element provided with a second feed point of a ground side. The antenna further comprises a linear third element which is arranged at a predetermined angle with the first element, with a vicinity of the first feed point and the second feed point as a center. The first element has an inductive property at a prescribed resonance frequency, and the third element has a capacitive property at the resonance frequency. The first feed point and the second feed point are provided at proximate positions, the second element is electromagnetically coupled with the first element and arranged substantially in parallel with the first element, and the third element is connected to a ground-side end portion of the second element.
