| With the increasing demands on miniaturized microwave and millimeter wave commercial products, such as those for wireless communication and collision avoidance radar, a high performance integrated system on package (SOP), which consists of surface mounted integrated circuits, embedded passives, interconnections between subsystems, has attracted tremendous attention in recent years. To accommodate this market trend, Low Temperature Co-fired Ceramic (LTCC) technology seems to be an optimal manufacturing option that has been widely accepted by the industry. In this dissertation, researches on SOPS for both microwave applications and millimeter wave applications are presented.; In the microwave application aspect, the research focuses on the development of an integrated antenna for short-range data communication SOP application and its implementation of SOP tags. A novel and efficient ultra compact folded meander line inverted-F antenna configuration is proposed and fully verified for microwave system on package applications. The antenna performance well matches the requirements for SOP application, especially for short-range data communication systems. Experimental results show that the antenna with less than 1/12th wavelength can achieve more than 4% within 2:1VSWR bandwidth. Design methodology of the proposed antenna is discussed under the aid of numerical study. With this proposed antenna and a novel integrated balun-filter combination function block, a mini 2.45GHz Bluetooth module and a 915MHz RFID tag are developed and functionally proved.; For the research on millimeter wave applications, a systematic study on fundamental passive circuits for millimeter wave system on package is conducted. These circuits include high performance millimeter wave transmission lines on LTCC, a high efficient radiation element on LTCC, and innovative integrated transitions among different type of transmission line. With the use of laminated waveguide and newly proposed transitions, a mixed feeding network configuration is developed. Loss analysis is carried out on this mixed feeding network to investigate its performance. In order to demonstrate the effectiveness of various proposed elements and architectures, a 16-element by 16-element array antenna using proposed high efficient radiation element, a quasi-cavity backed patch antenna, is developed and fabricated on a 5-inch by 5-inch LTCC tile. The proposed individual functional elements are also loaded on the back of the manufactured array antenna tile. The whole system is designed to work at 29GHz, which is one of Local Multi-Point Distribution System (LMDS) working band. (Abstract shortened by UMI.)... |
