الملخص

With the widespread use of communication devices, companies are competing to provide better devices to the user, aiming to offer small sizes, lightweight, and at affordable prices. As the filter is one of the most important stages in these devices, many studies have focused on minimizing size and weight by reducing the number of filters by developing them into reconfigurable ones.In this thesis, the compact band-reject filter employing the U-shaped slot that is etched on the microstrip line was thoroughly investigated aiming to develop it into a reconfigurable filter. The CST Studio EM software was used in the simulations. The slot parameters were found to control the resonance frequency and bandwidth. The developed filter provided two states of all-pass and band-rejection at 2.45 GHz by inserting a PIN diode switch at the center of the slot. The ON and OFF states of the PIN diode were represented by short and open circuits, and then the equivalent circuits for the two states were implemented. The distribution of the electric field around the U-slot was investigated and found useful for understanding how the filter works. To verify the proposed design a vector network analyzer was used to test the fabricated. The fabricated filter offered an insertion loss of 14 dB at the reject band and about 1dB for the all-pass state.The idea of the U-shaped slot was developed into a few configurations including a meandered slot filter. Detailed investigations of the proposed designs are given. The results showed that the designs can offer bandwidth reconfiguration by simply switching a single PIN diode. The proposed designs are applicable to a wide range of applications requiring small size and reconfiguration
