Vehicle antenna and diversity receiving apparatus

A diversity receiving apparatus comprising:

• a plurality of antenna elements which are fixed to a dielectric portion in an exterior part of a vehicle body and whose power supply points are disposed closely;
• a high-frequency grounding member which is disposed in the vicinity of the power supply point of the plurality of antenna elements and which is fixed to a conductive portion of the vehicle body so as to be capacitance-coupled for carrying out electric grounding in common with regard to a high-frequency component;
• an amplifier which is disposed in the vicinity of the power supply point for amplifying a high-frequency reception signal which is inputted from the power supply point;
• a switch which is disposed in the amplifier for selecting an antenna element for amplifying a high-frequency reception signal;
• and
• a selective reception unit for selecting an antenna element by which good reception quality with regard to the high-frequency reception signal is obtained by carrying out processing of the high-frequency reception signal which is amplified by the amplifier and by controlling the switch remotely.
