ABSTRACT:
Even though an antenna apparatus is low profile to have a height of not more than 70 mm, sensitivity is maximally suppressed from being deteriorated. In an antenna case10projecting from a vehicle in a height of not more than 70 mm, an antenna circuit board30on which an antenna pattern is formed is uprightly arranged and an amplifier circuit board34which amplifies a received signal output from the antenna circuit board30are housed. In the antenna circuit board30, an antenna coil to resonate the antenna pattern in an FM waveband is inserted between the antenna pattern and a feeding point. Therefore, a low-profile antenna pattern having a length which is about 1/20 a wavelength of an FM broadcast resonates the FM band.
