碩士 === 國立中央大學 === 通訊工程學系在職專班 === 101 === Due to the progress of technology and science in these years, the TV products are developed flourishingly. Obviously, the TV products have been transformed from transmission based on analog signals to Digital Video Broadcasting – Terrestrial signals. Recently, there is so-called Smart TV, which could be incorporated with the functions and the use of Broadband Networks. Hopefully, the functions of TV products will be improved with the science and technology development. This thesis will focus on two kinds of antennas, which can be applied for the indoor and being conformed with the digital TV reception antenna of band of Taiwan, which includes the planning DVB-T2. For coping with the tendency of TV product development, these two antennas are designed for broadband，and the bands of communication systems in Taiwan, such as GPS、DCS1800、WCDMA Band1, and WLAN are included. These two antennas are designed based on the asymmetric and symmetry monopole antenna types, and they use the Micro-strip line structure for the way of feeding the energy. After using the basic theory of antenna design to calculate the required size of antenna initially, then we perform the simulation and the analysis by Ansoft HFSS and make the physical model with FR4 board. At last, we passed the efficiency and gain volume test of Chamber to produce the physical antenna which may be adopted as the practical use for the multi-band communication systems in Taiwan.
