| dc.description.abstract | 本論文主要是探討利用共平面波導結構來實現GPS射頻前端接收機模組，其中包含三個部份，分別為天線、帶通濾波器以及低雜訊放大器。天線部分以多頻共振的原理，在不影響增益及方向性前提下，使頻寬由1.5%提升至3%；帶通濾波器則利用慢波（slow wave）結構，使得在頻寬及插入損失之間取得平衡時，尺寸能夠大幅縮小；最後低雜訊放大器則以 型共平面波導不連續結構來完成，使得匹配網路更加穩定，並提供16.5dB的增益值。在設計過程中，皆針對結構中每一個重要參數對S參數的影響以及實作的可行性來加以討論，尋找簡易設計的程序，並且對設計時可能遭遇到的問題，以理論的方式分析並提供可行的解決辦法。 | zh_TW |
| dc.description.abstract | In the thesis, a RF front end for GPS receiver is designed using coplanar-waveguide structure. Three parts of the receiver are mainly considered：antenna, band pass filter, and low noise amplifier. Based on the principle of the multi-band resonance, the bandwidth of the antenna is increased for 1.5% to 3%, compared to single patch antenna. Moreover, it is done without sacrificing antenna gain. The filter is designed using slow-wave structure, and therefore the size is reduced significantly. The noise filter is designed using the -type CPW discontinuities, 16.5dB of gain of LNA is obtained. Every effects of important parameters on S-parameter and experiment feasibility are investigated. At the end simple design procedures are presented. | en_US |
