First of all, based on transmission-line theory,different kinds of transmission line are used, for example : a microstrip line, strip line, coplanar waveguide transmission line to derive different types of properties, and then take advantage of the characteristics of the transmission line to obtain the electrical characteristic parameters of substrate. We will use similarity matrix which has the same eigenvalues and use the ring resonator method to extract and verify the accuracy of the parameters. Also additional effects, such as surface roughness and a variety of transmission lines and electrical characteristic parameters of multilayer substrate will be extracted. The second part is about antenna design, including antennas used in 5G communications base station antennas and 24GHz automotive collision avoidance radar.The antenna for 5G uses the substrate from Boardtek and we use a series-fed antenna to increase antenna gain. Equal amplitude excitation is used at Ka band, at the center frequency of 38GHz. Next, the antenna at 24GHz for automotive radar is designed using Rogers RO4003C substrate. In order to suppress the amplitude of sidelobe, a taper distribution of excitation is used. 盧信嘉 2016 學位論文 ; thesis 87 zh-TW |
