Patent number: 7277059Abstract: A monopole antenna assembly mounted onto a bracket (2) of an electronic device includes an electronic connector (1) having a long contact (12) extending outwardly. The long contact acts as a radiating element of a monopole antenna. The long contact can be easily obtained by modifying the size of contact in stamping process. The connector electrically and mechanically cooperates with a socket, such as a female connector, of the electronic device. Thus an electrical path is formed between the monopole antenna and the electrical device via connector and the socket.Type: GrantFiled: May 7, 2004Date of Patent: October 2, 2007Assignee: Hon Hai Precision Ind. Co., Ltd.Inventors: Hsien-Chu Lin, Lung-Sheng Tai, Chia-Ming Kuo, Zhen-Da Hung
