ABSTRACT:
An automobile antenna disclosed is built in within a vehicle body without any externally protruding portion. It includes an electromagnetic coupling type high-frequency pickup, which has a loop antenna disposed in close proximity to a marginal edge of the vehicle body so as to electromagnetically detect the high-frequency surface currents induced on the vehicle body by external electrical waves.
The loop antenna is formed into a coil of a plurality of turns so that it has a resonance characteristic with respect to frequencies in a broad band by virtue of the self inductance and the parasitic capacitance of the coil.
