6. INTRODUCTION Bandpass filters are a vital part of the communication system. Microwave filters with compact, miniaturized size and high performance left a remarkable impact on wireless communication systems. The filters composed of the fed lines connected to the two ports with the parallel coupled lines between them are called Microstrip bandpass filters.

13. Literature Review 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].

14. In Ala'a [17], a non-uniform bandpass filter with a defected ground structure (DGS) is presented. The width of the presented filter was obtained using an improved operation with a U shape and non-uniform form. Moreover, a DGS is employed to acquire multiple bands. The proposed design was implemented using high-frequency software such as HFSS and CST-Studio. Another methodology for designing harmonics was a suppressed microstrip ultra-wideband (UWB) BPF proposed in Bi [18]. In Chakravorty [19], a collaborative split-ring resonator technique is adopted to anticipate the center frequency and design of microstrip bandpass filters that are generally below the class of heuristic structures. Bent transmission lines are often needed to minimize channel structures physically; however, in the hypothetical (planned) prediction of complete or focal frequencies for the bandpass channel plan, ebb-and-flow effects may cause errors. Previous suggestions on bend corrections were accurate, but continuing structure standards require an improvement in accuracy.

15. INFERENCE DRAWN OUT The interdigital structure is a combination of stubs and it can be modified . Bandpass filters can be designed for any frequency range. Notch can be created for any desired frequency. Filter performance can be improved by using resonators with defective microstrip structures The size of the filter can be reduced by using defective microstrip structures (DMS) in micro-strip resonator. Transmission zero can be adjusted.
