Abstract
The present application discloses a glass antenna arranged on a vehicular window glass. The glass antenna includes: a feeding terminal connected to an antenna amplifier; a first antenna connected to the feeding terminal and set so as to receive a radio frequency signal in a first frequency band which has a first wavelength at a central frequency of the first frequency band; a coupling element having a length set based on a length obtained by multiplying one-half of the first wavelength by a glass reduction rate, coupling element being connected to the feeding terminal; and a second antenna capacitively coupled to the coupling element and set so as to receive a radio frequency signal in a second frequency band which has a second wavelength at a central frequency of the second frequency band.
