Design of triple-band internal chip antenna for mobile handset

In recently, the ubiquitous techniques are studied vigorously in many research areas. The important techniques of these ubiquitous areas are RFID (Radio Frequency Identification) and WiBro (Wireless Broadband) service systems. In order to service these two techniques into the mobile handset, the integrated antenna design technology is studied explosively [1][2]. Specially, the antenna characteristic is deteriorated by interference of parts, which is arranged in the handset. Therefore, in the internal antenna design environment at consideration is needed. In this paper, the mobile RFID/K-PCS/WiBro chip antenna, which is suitable for the equipment of mobile handset of slide type, is proposed.
