| The transmitter is an important part of Radar system, so its performance directly affects the Radar system's work. This thesis is based on the research of the transmitter's pivotal technology, including the design of microstrip-coupled slot antenna array and third-class power amplifier. Microstrip-coupled slot antenna array and power amplifier are analyzed by theory and engineering respectively. With the help of the simulation HFSS,CST and ADS software, microstrip-coupled slot antenna array and third-class power amplifier are designed and simulated in X wave band, the detailed work includes:(1)The microstrip-coupled slot antenna array is simulated and designed by the HFSS and CST software. It is analyzed in 8.76GHz which is its center frequency, including VSWR<2,band width≥200M,pattern meets condition.(2)With the ADS software, third-class power amplifier is simulated and designed. It is analyzed in 8.76GHz which is its center frequency, including Gain≥10dB,band width≥200M,1dB-power-compression point is 33dBm.(3)Finally, the microstrip-coupled slot antenna array and third-class power amplifier are made by AutoCAD and Protel soft. The test result shows that the components can meet the requirement of the transmitter system by circuit test. |
