為因應未來車內廣播接收、無線通訊與多媒體應用的多元化需求，車輛天線系統的設計乃朝向多功能天線設計，其中包含了 AM、FM、DTV、GSM、GPS、DCS及WLAN等頻帶天線與低雜訊放大器。本論文提出車用整合式天線模組之設計，其中乃應用前人所研究之晶片天線與市售天線來進行研發與整合。由於晶片天線本身具有微型化與隱藏式等優點，因此相當適合安裝於車體內而不會影響其外觀或結構。本研究應用電磁數值套裝模擬程式HFSS來分析GSM、GPS、DCS及WLAN等多款微型晶片天線之輻射效能，並探討天線之間的耦合影響，以設計出適當之整合天線模組架構並加以驗證之。此外，為了增加天線接收靈敏度，本研究亦設計適用於DTV及GPS頻帶的低雜訊放大器來改善之，並使用HFSS及ADS電路模擬軟體來進行多頻帶整合式天線之效能分析，以達到較佳之設計。

In order to meet the various receiving requirements of broadcast system, wireless communication and multimedia applications for vehicles, the automotive antenna system must integrate various antennas and low noise amplifiers to achieve the specific applications, such as AM, FM, DTV, GSM, GPS, DCS and WLAN signal receptions.
This thesis is to propose an integrated antenna module composed of chip antennas and commercial antennas for modern vehicles. Those chip antennas not only have miniaturized dimensions, but also can be built-in RF devices more flexibly. Thus, the chip antennas are very suitable for installing in vehicles without changing the configurations of the vehicles.
In addition, the radiation performance and mutual coupling for both of GSM, GPS, DCS and WLAN antennas have been performed by using a commercial simulator, HFSSTM. Thus, the suitable structures of the antennas can be designed and verified from above analyses to meet the specific automotive requirements.
Furthermore, this study designs two low noise amplifiers (LNA) to increase the sensitivity of wireless receiver for enhancing the DTV and GPS systems. Also, an antenna module composed of all antennas and LNAs are designed by applying the HFSS and ADS simulators to achieve better performance.
