Abstract
The application of microwave sensor has played many parts in industries such as aviation, telecommunication, medical, food, and many more. Microwave sensor is a device that detects short wavelength to extract information without having to touch the materials detected. In industry such as rice industry had utilized the application of microwave sensor to classify the rice quality and categorized it according to its price. The devices that are widely used such as ‘Sinar AP model 6060’ or Scanning Electron Microscope is effective at detecting quality of rice. However, the prices of these devices are substantial. This thesis investigates on the wideband band pass filter design operation and design wideband band pass filter as a low cost microwave sensor for characterizing quality of rice. The technique employed in designing the filters is broadside-coupled microstripslot technique. The filter is design and simulate by using electromagnetic simulation tools. There are three filters to be designed and the results are compared. The insertion loss and return loss is analysed. Insertion loss means that the loss of signal during transmission in a device whereas return loss means the loss of power due to its being reflected to its source Therefore, a good characteristic for a filter is that with high return loss and low insertion loss. As all the filter were optimized and the results were determined, the filters were fabricated. This thesis concludes that Type 2 performs the best compared to Type 1 and Type 3. The results obtained shows Type 2 has the highest return loss which is 25.32 dB and lowest insertion loss which is 0.15dB
