Abstract (en)
Disclosed is a glass antenna 10 which comprises: an FM-digital radio antenna element 20 configured to receive a high-frequency signal in an FM broadcast band of which center-frequency wavelength is a first wavelength and a high-frequency signal in a digital radio broadcast band of which center-frequency wavelength is a second wavelength; a first conductor wire 30 formed to have a length set based on a length equal to one-half of the second wavelength; a second conductor wire 40 connected to one end of the first conductor wire 30, wherein the second conductor wire is formed to have a length set based on a length equal to one-quarter of the second wavelength, and disposed adjacent to the FM-digital radio antenna element 20 such that it is capacitively coupled with the FM-digital radio antenna element 20; and a feeding terminal 45 connected to the other end of the first conductor wire 30, wherein the feeding terminal 45 is disposed on a vehicle-width directional outer portion of the vehicle window glass 1 to be covered by a rear pillar cover 2.
