发明名称 Multiple band antenna apparatus
摘要 An antenna apparatus capable of receiving AM radio broadcasting and FM radio broadcasting and being realized at a low cost includes an FM antenna conductor for receiving FM broadcasting formed with a metal pipe with good conductivity, and an AM antenna conductor for receiving AM broadcasting housed in an internal space of the antenna conductor, so as to unify an AM antenna and an FM antenna with a simple structure. The FM antenna conductor also functions as an electrostatic shielding member for the AM antenna conductor, so that high-frequency noise from other equipment is prevented from being received at the AM antenna conductor as interference noise without raising the cost.
