碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 96 === This main propose of the paper is to design a LTCC chip antenna and for an embedded handset communication device. To achieve the miniaturization at lower frequency band by adjusting to the parameters of substrate for improving the bandwidth improvement. This advantage of designed antenna lies in the simple structure antenna manufactured using the sole level on the metal medium foundation plate. The present paper will discuss two subjects. The first subject is to design the ceramic chip antenna with LTCC technology to apply frequency band in the Global Positioning System (GPS). The second subject to discuss ceramics substrate of this antenna use, and extends with the designed antenna structure by changing the parameter of substrate corresponding to the feature of antenna to operate at 1.575GHz frequency band, with suitable coefficient value. Finally, the simulation results are approved by the results of experiments. We get the bandwidth is 160MHz, and return is -12.9dB, although antenna center frequency and conclusion of simulate vary about to 20MHz, it still could be used in GPS.
