“…One promising technique is by using microstrip structure.Since resonators are the basic component of the microstrip filter, it is requisite to select a proper resonator for filter design. Out of various bandpass microstrip filters, the rectangular ring resonator is one of the most preferred [13][14][15][16][17][18][19][20][21].…”

A simple procedure for designing a highly selective microstrip bandpass filter of second order is presented in this paper. The proposed filter is composed of two principal square open-loop resonators and designed with planar structures on a Roger substrate. It is intended for 5G applications, especially for Sub-6 GHz range frequency [3.5–3.8 GHz]. The suggested band pass filter has a very attractive compact size of 7 mm × 15.46 mm. The performance of this simple miniaturized filter, which is characterized by high selectivity in the band of interest, can be seen from its important characteristics: Adaptation, Transmission and Coupling Coefficients. The electromagnetic simulations and measurement results are in good agreement, which validates the design idea and procedure.

“…Recently many mm-wave RF devices have been developed. [1][2][3] In Reference [4], the authors design a differential highly selective millimeter-wave filter with multistage transmission lines. The designed bandwidth is very wide, but the actual test result is not good due to the technological level limitation.…”

“…But the working frequency is much higher, resulting in worse energy loss of electromagnetic radiation, and the fractional bandwidth (FBW) of the working frequency band is smaller, which also puts forward more stringent requirements on the process and performance of the relevant devices. Recently many mm‐wave RF devices have been developed 1–3 …”

In this article, a high selectivity mm-wave filter chip based on integrated passive devicies (IPD) technology is proposed. Two adjustable transmission zeros are introduced on both sides of the passband to achieve high roll-off characteristic. The odd-even equivalent circuits are used to analyze and calculate the Sparameters, and the procedure to design a filter is given. Finally, two filter chips with different bandwidths are manufactured based on IPD technology.The measured results show that the minimum insertion losses of the two chips are 1.82 and 1.39 dB, respectively, and their return losses are better than 15 dB. In addition, their roll-off and stopband suppression are of high level, and the chip sizes are only about 2.8 Â 2 mm 2 .

“…In this paper, the proposed diplexer design is based on two microstrip planar band pass filter (BPF) structures printed on Rogers RT/duroid 6010LM, in which each one is based on resonators technique [14][15][16][17][18][19][20][21]. The first BPF is designed for the lower range frequency [1.7 GHz to 1.9 GHz] fixed for 4G-LTE applications, while the second is designed for the higher range frequency The proposed diplexer model is low cost and light weighted due to the implementation of microstrip technology.…”

This paper presents the design of a high isolation miniaturized compact diplexer model based on Band-Pass Filter technique, which is intended especially for a lower band [1.7 GHz to 1.9 GHz] fixed for 4G-LTE and a higher band [3.4 GHz to 3.8 GHz] fixed for 5G Sub-6 GHz. The designed diplexer is very compact with an overall size of 11× 36.49 mm2. The proposed design method is implemented by directly combining two band pass filters (BPFs) with separated electric and magnetic coupling distribution and designed with planar structures on a Rogers RT/duroid 6010LM substrate with a relative dielectric constant of 10.2, which simplifies significantly the design process of diplexer. The performance of this structure is presented and discussed in terms of its important characteristics: Impedance matching, Transmission losses and Isolation. Good agreements between simulated and measured results are achieved, which successfully verifies the proposed design method.
