| Summary: | 碩士 === 國立臺灣海洋大學 === 機械與機電工程學系 === 95 === The aim of this paper is to design a compact slot UWB antenna and discuss the band-notched function. And the slots that have different form can achieve the UWB antenna standard. The proposed antenna utilizes the advantages of the CPW line to simplify the structure of the antenna into a single metallic level, thereby making easier the integrated circuits. And it also conformed to the requests of many consumer products and communication facilities that concerned with small size, light weight and low cost.
First, the wideband mechanism and radiation patterns of a traditional cylindrical dipole antenna are discussed. Based on the mentioned consideration of the traditional cylindrical dipole antenna, a planar UWB antenna with CPW-fed can be implemented. And I discuss the band-notch function by inserting two proper slots in the interior of the radiation element. Next, the wideband of the slot antenna is also discussed. Base on the mentioned consideration of the slot antenna, a compact slot UWB antenna with CPW-fed can be implemented. The fed of the slot UWB antenna is to part of capacitance coupling. Finally, adding the band-notch function in the antenna can have good effect the same. In this thesis, a small printed UWB antenna conformed to FCC standard (3.1 ~ 10.6 GHz) is proposed. Details of the experimental results of the purposed antenna are presented and discussed.
