| Popis: | 90 This thesis aims at designing microstrip bandpass filters with compact size. Coupled stages with folded lines are used. To make the effectiveness in reducing the circuit size as efficient as possible, both the width and gap of the coupled microstrip lines are chosen as small as possible. We analyze and compensate the folded resonators and coupled folded resonators, so that bandpass filters can be constructed with coupled multiple folded lines. A scheme for design coupled stages with an arbitrary coupled length is also incorporated into the design, for the convenience of resonator folding. Several Chebyshev filters of orders three and five are fabricated and measured to demonstrate the idea. |
