“…Then, this requirement constitutes an appropriate test for the technique described in Section 2. Second, the highly crowded frequency spectrum for wireless communications has made band pass filters very useful components in many types of RF and microwave circuits (Ng et al , 2002). Third, coupled‐line filter structures can be made with the fabrication technique of this study.…”

PurposeThe purpose of this paper is to share valuable information about low‐cost microwave circuit research with academic and industrial communities that work, or want to work, in this field.Design/methodology/approachScreen‐printing technology has been chosen as the fabrication method because of simplicity and low costs. Different materials and printing parameters were tested in four generations of microstrip lines. After obtaining a satisfactory fabrication method, passive microwave components were printed, assembled, characterized and modeled.FindingsResults demonstrated that the proposed low‐cost method allows fabricating low loss microstrip lines (15.63×10−3 dB/mm at 10 GHz), filters, inductors, and capacitors that work well up to 12 GHz.Research limitations/implicationsModel accuracy of inductors and capacitors can be improved. The use of more precise calibration and de‐embedding techniques is necessary. More components can be fabricated and modeled to increase the flexibility and applicability of the proposed fabrication method.Practical implicationsThe presented information can help limited budget companies and small educational institutions in electronics to fabricate microwave circuits at low costs. This is an excellent approach for students who want to learn how to make microwave frequency measurements and circuits without the need of expensive fabrication equipment and clean rooms.Originality/valueThe step‐by‐step fabrication method described in this paper allows fabricating different microwave components at low costs. The presentation of electrical models for each component completes the design‐fabrication cycle. As this information is gathered in a single source, it makes easier the incursion of new actors in the microwave field.

“…By reducing the substrate thickness, the track separation becomes smaller. However, this small track separation can be a problem during the circuit fabrication [4]. The trade-off between substrate thickness, minimum coupling gap, characteristics impedance and overall loss is a very important issue that needs to be considered to achieve the required filter performance.…”

Abstract-Growing demand for mobile and wireless communication systems has generated much interest in low-cost, high quality microwave fabrication technologies. The performance of these systems relies on not only excellent design and analysis but also the characteristics of materials and their corresponding fabrication technologies. Often the designer is faced with a compromise between satisfying the high performance demands of a microwave component, and achieving low fabrication cost. This paper studies feasibility of realizing microwave bandpass filters using thick film screen printing techniques. The measured and simulated results for a 9.5GHz edge coupled bandpass filter have been determined and compared.

Studies have been conducted on edge-coupled bandpass filters as the component used to assess the performance of the multilayer circuits and fabrication error at various frequencies (5GHz and 25GHz). The outcomes of the work showed the performance benefits that accrue from the use of multilayer circuits, in terms of a significant improvement in bandwidth while maintaining the quality of the filter roll-off. An analysis of the fabrication errors provided useful guidelines for deciding the degree of alignment accuracy needed for a certain application, and presented data not previously reported in the literature. A particularly significant error that was quantified was that of skew between conductors on different layers, where it was found that a skew angle of only 0.1° resulted in very significant changes in bandwidth and insertion loss.
