Abstract (en)
It is provided a glass antenna to be arranged on a window glass of a vehicle, comprising a first antenna (3) configured to receive a radio wave in a first frequency band, and a second antenna (4) configured to receive a radio wave in a second frequency band having a frequency that is approximately half of a frequency of the first frequency band. The first antenna (3) including a core-side feeding unit (36) and an earth-side feeding unit (31) to be coupled to a receiver, a core-side element (37) extended from the core-side feeding unit, and an earth-side element (32) extended from the earth-side feeding unit. The core-side element (37) having a length approximately equal to a length obtained by multiplying a wavelength at a center frequency of the first frequency band by a wavelength shortening rate of glass.
