| 總結: | Studies on the microstrip antenna array has been conducted with the objective to design, simulate and fabricate the microstrip antenna array operating at 12GHz, Ku band downlink. Microstrip antenna is well known for its low cost, compact and mechanically robust. This project explores the capability of the microstrip antenna array at a higher frequency for the satellite communication. Specification is defined and the designed antenna should be able to operate with minimum gain of 20dBi, <- 10 return loss, 3 to 5 percent bandwith with circular polarization. Simulation started with the basic single element antenna in getting the correct geometrical parameters and feeding technique. Simulation was done step by step prior obtaining the final design of antenna. The final design which complies to the specification was selected for fabrication and measurement, whereby in this case (16x16) array was selected. Fabrication was done successfully, however the performance comparison shows some variation between simulation and antenna measurement. There are many factors contributing to the variation which has been discussed in Chapter 5 of this writings. This project work has shown a big potential of microstrip antenna array in satellite communication, at a higher frequency. Further effort and follow ups will enhance the performance of the microstrip antenna and lessen the impact of the shortcomings. |
