Recently, wireless-PAN systems using a UWB technique are considered. Antennas such as a planar trapezoidal monopole or dipole antenna for a UWB was developed.[1],[2] Since a 5 GHz band is allocated for wireless LAN service such as an IEEE802.11a, a UWB antenna should have a band notch to avoid an interference between two systems. To fulfil this requirement, several UWB antennas having a band notch developed. And many band notched antennas at 5 GHz band have reported.[3],[4],[5] As the next stage, the antenna of a terminal equipment for a wireless PAN or a wireless USB is required. In these applications, the antenna have wide bandwidth or multi band and has to be small in order to be installed in size of 10 mm by 30-40mm, which was USB memory size of a terminal side equipment.[6],[7]
