Abstract
An automobile antenna including a defogging heater wire and a conductor combined into a simple structure for a good FM reception. FM choke coils, which prevents high-frequency signals from being transmitted from power supply circuit to the heater wire, is installed between the heater wire terminal and the power supply circuit for the heater wire, and the heater wire which resonates in the FM frequency band but not in the AM frequency band is inductively coupled to the conductor which is installed on the surface of the window glass and can resonate in the FM frequency band but not in the AM frequency band. The heater wire and conductor are installed in such a positional relationship as to create a double resonance.
