Summary:
In recent years, various kinds of wireless mobile communications have been developing rapidly. Therefore, multi-band mobile devices are required for wireless services such as mobile phones, GPS, television broadcasting. In order to integrate mobile services, a multi-band antenna is needed. In this paper, we propose a novel multi-band antenna using plural conductive wires with a coupling phenomenon. This antenna is constructed in a simple structure. Using a coupling phenomenon between wires, the currents of particular modes are excited on the antenna to give the multi-band characteristics. The operating principle of the proposed antenna will be presented more in detail. The design of operating frequencies, the bandwidth widening and the radiation characteristics are investigated.
