“…Further development in filter microwave design based on concepts of single band-pass and differential band-pass filters has been illustrated in [11]- [12] using dielectric resonators. Micro-strip line based band-pass filters offer advantages such as light weight, compact, robust and conformal structure, low profile and easy integration with MMIC chips have been proposed in [13]- [14] [ Fig. 2 a) and b)].…”

The new design methods of microwave filter has proved its significance for use in wireless communication systems. Modern wireless communication systems require microwave filters to have stringent specifications such as compact size, robust, conformal, light weight and more importantly cost effective while maintaining its electrical characteristics. Micro-strip filter design and reconfigurable filters present a better prospectus in this regards as it meets the specifications of modern wireless communication applications. Reconfigurable filters can provide control over parameters such as frequency, bandwidth and selectivity while reducing the need of number of switches sandwiched between electrical components. Different methods have provided a new dimension for designing microwave filters .In this article, we present a review on design methods for reconfigurable band-pass filters for next generation wireless technologies such as 4G, 5G and IOT.

“…In this letter, a novel approach for the design procedure of the microstrip line filter which comprises of analysis of attenuation characteristics, prototype values, odd even impedance method, separation of coupled lines is proposed [7,8]. Using this method the electrical performance parameters of the proposed filter structure are drastically enhanced [9,10]. The proposed filter design and performances are analysed and optimized using Computer Simulation Technology (CST microwave studio).…”

In this paper, a novel approach for designing the parallel coupled microstrip bandpass filter operating at C-band frequency is numerically analyzed iteratively and simulated. The physical dimensions are being finalized using standard odd-even impedance method. Various electrical parameters such as insertion loss, reflection loss are being analyzed and practical results are being compared and found same as the predicted results. The proposed design is fabricated on FR4 dielectric substrate and the experimental result shows the scientifically acceptable for C-band Applications.

“…In order to suppress the spurious passbands, many methods has been presented such as methods using the stepped-impedance resonators and grounded-step-impedance resonators [11,18,20,23,25,26], fractal-shaped micro-strip [12], multiorder resonator [13], T-stub/DGS [14], antisymmetric modied antiparallel coupled-lines [15,19,21], branch stubs co-via structure [22], DGS and Spur-line Coupling Structures [24], etc.. However, the size of structures above is not small enough and the higher frequency spurious passbands can not also be suppressed efficiently [10][11][12][13][14][15][18][19][20][21][22][23][24][25][26]. Openstub and air-bridge have been introduced to create transmission zeros around 3f 0 and 5f 0 in a compact filter [16].…”

A novel slot-line filter with stop-band up to 30 GHz is proposed in this paper, and the theoretical analysis is illustrated in detail. This filter is designed on a Rogers RT/duroid 5870 substrate. The rectangular micro-strips can generate transmission zero to give a great suppression for the spurious response around 5f 0 while the L slot lines can create transmission zeros to suppress the spurious response around 7f 0 , 9f 0 and 11f 0. f 0 is 2.43 GHz in this paper and represents the center frequency of the main passband. The compact size of this novel filter is 23.7 mm * 14.725 mm (0.152λ * 0.103λ (λ is the working wavelength of this filter)). Besides, the external quality factor of this filter can be as high as about 29.6. To demonstrate the transmission function, the compact filter has been fabricated and the measured results show the feasibility of this structure. 1. INTRODUCTION With the development of modern communication technology, WiFi and blue-tooth applications require small-sized filters with wide stopband. Microstrip bandpass filters with low insertion loss, compact size and high Q play more and more important roles in mobile communication systems and radio frequency (RF) front/end of the wireless communication systems [1-4]. Planar bandpass filters (BPFs) having compact size and a very wide stopband are very popular to implement the radio frequency (RF) front end in microwave communication systems [5]. As is konwn to us that the micro-strip filter
