Patent number: 5541615Abstract: A three band antenna unit for reception of radio waves in the AM and FM bands and for reception and transmission of radio waves in the UHF band as well as its connection with filters and a communication equipment are disclosed. The antenna unit includes an upper, first element for reception and transmission of a radio wave in the UHF band and a lower, second element for reception of radio waves in the FM band, both connected to a mobile telephone. An AM band signal from the first element is transmitted to the lower, second element through an AM band pass filter. A radio wave signal from the lower, second element is transmitted to an AM/FM tuner through an AM/FM band pass filter.Type: GrantFiled: March 28, 1994Date of Patent: July 30, 1996Assignee: Aisin Seiki Kabushiki KaishaInventors: Eiji Koide, Yuichi Murakami, Akimasa Yoshida, Kiyokazu Ieda, Kazuo Sato
