Ahmed Sayed Ismail Amar;
Abstract
This thesis discusses one of the modern microwave receiver systems in the range of Ku-band applications as satellite receiver for unmanned vehicle and some other applications. The main objective of this thesis is conducting for a case study and design dual band receiver in the downlink and uplink carrier in Ku-band achieving multifunctional, low cost and reduced size.
• Chapter One: This chapter is an introduction about microwave systems, receiver architectures, the proposed RF front end receiver operating frequency and the system specifications.
• Chapter Two: This Chapter discusses the RF front end receiver parts. Firstly, we describe the definition of microstrip antennas, definition of basic and important antenna parameters. Secondly, we begin with the basic concept of filter and its types, then important characteristics for the microstrip filter. Finally, for a fundamental understanding of the Low Noise Amplifier procedure, we introduce a series of underlying concepts.
• Chapter Three: This Chapter discussesthe following steps for designing the dual band RF front end receiver components separately. The first step explains the design of conventional shape for rectangular microstrip patch antenna at two different frequencies. Then, we introduce steps of design of rectangular patch with slits. The proposed antenna is fabricated and measured. We compare between the simulation and measured results which achieved the required goals.
The second step is the procedure for designing the conventional shape of microstrip parallel coupled line bandpass filter at the uplink and downlink of Ku-band. Next, we design, simulate and fabricate the wide band filter which have good agreement results between simulation and measured results. Then, we design and fabricate the proposed dual band filter using a microstrip parallel coupled, half-wavelength resonator with tuning capacitor in series with coupled sections which achieved the required goals.
The third step starts with features and important characteristics of the Low Noise Amplifier transistor at the Ku-band. After that, we begin the Low Noise Amplifier design with the DC analysis. Then design the biasing network, matching input/output network, and finally connect the sub networks together, to achieve the required goals. Finally, the S-parameters of each component in our system are transferred to the CAD tool, and the final results are found to meet our goals.
• Chapter Four: This chapter discusses the implementation of RF font end receiver in lower L-band.We started with the proposed wide band antenna specifications, and the design steps of the circular patch antenna with u-slotted and partial ground. We fabricated the proposed antenna and measured the different parameters and results are found to achieve our goals. Next, we present a wide band microstrip parallel coupled line filter. We designed, simulated and fabricated the wide band filter which have good agreement between simulation and measured results. After that, we introduced the low noise amplifier specifications with its features and important characteristics and measurements, and results are found to achieve our goals. Finally, we measured and simulated the proposed system and the results are satisfying our goals.
• Chapter Five: This chapter discusses conclusion and future work for this research point.
