• Bandpass filters are a vital part of the communication system. Compact and miniaturized design aspects of
filters play an important role in a fast data transmission system. Microwave filter with small sizes and high
performance has left a remarkable impact on the wireless communication system. Resonators are being a
necessity in the construction of microstrip filters [1-7].
• The small size of the resonator will result in the compactness of the filter. By reducing the size of the filter, we can
modify the resonator structure or the traditional resonator, from this we can create additional modes with better
performance and small area. [8-10].
• Modified resonators can be handled as multiple resonators. Compact size multimode resonator has relatively low
attenuation within the filter designing process. coupling among the degenerate modes is quite a difficult process for
filter designing with high performance using a single multimode resonator when compared with multiple multimode
resonators. In most of the designed multiple multimode resonators, the parasitic resonance operates close to
fundamental modes [11- 16].](https://image.slidesharecdn.com/presentationfinalyear-240926052844-a09d7713/85/Presentation-final-year-on-advanced-design-sysytem-13-320.jpg)
