碩士 === 國立臺灣科技大學 === 電子工程系 === 94 === In this paper, we will design miniaturized and wideband antennas in order to apply in different environments. We will discuss about three kinds of antennas, meander-line antennas, bow-tie antennas and untra-wide band antennas in three sections. In these sections, we will do simulations by full-wave simulation software IE3D and realize them using FR-4. After all, we will measure the S parameters of three antennas by using a network analyzer and the patterns in a chamber to understand the real characteristics of three antennas. It is important to combine an antenna with the circuit for a completed system. We will also discuss how to realize the impedance matching between the antenna and the circuit to achieve the biggest power output in this paper.
