Abstract

A glass antenna includes a shared antenna conductor which meets a first frequency band and a second frequency band higher than the first frequency band and a feeding part connected to the shared antenna conductor. The shared antenna conductor includes a first element extended from the feeding part as a starting point and a second element extended from the first element as a starting point. At least a part of the first element and the second element configure a semi-loop form. When a wavelength in air in a central frequency of the second frequency band is λ, a glass shortening coefficient of wavelength is kand λ=λ·k, a conductor length of the first element is 0.65 λor higher and 1.0 λor lower, and the shortest distance between a defogger provided in window glass and the shared antenna conductor is 15 mm or longer.
