Patent number: 8902109Abstract: A communication device includes a assembly and an antenna structure formed on the assembly. The antenna structure has a feeding antenna and a stub antenna spaced apart from the feeding antenna. The feeding antenna has a feeding portion. The stub antenna is suitable for being excited and coupled by the feeding antenna, resonating at a resonance frequency of the feeding antenna, and causing the antenna structure to form two hotspots in an operated frequency band. The shortest distance between the feeding antenna and the stub antenna is defined as a coupling distance. The coupling distance is larger than zero and smaller than or equal to the length of the stub antenna. Thus, electric field value generated from the feeding antenna can be reduced by the stub antenna being excited and coupled by the feeding antenna and resonating at the resonance frequency of the feeding antenna.Type: GrantFiled: February 5, 2012Date of Patent: December 2, 2014Assignee: Auden Techno Corp.Inventors: Chi-Ming Chiang, Chun-Chuan Chang
