“…It has also shown that the multilayer CPW MMIC bandpass filter can be realized at frequency 28 GHz by utilizing a resonator with length of 1,057 µm. Another important study explained in this work that the size of the perturbation within the filter increase the coupling coefficient of even-odd mode to obtain more bandwidth for the bandpass filter [19]. When even-mode applied, an open circuit due to a magnetic wall occur along the symmetry plane and the total signal (𝑆 𝑒 ) leaving the input port, given by ( 5) [21], [24].…”

“…In the previous work, we presented the multilayer CPW MMIC bandpass filter using a meander resonator for X-band transceiver application at frequency 10 GHz [19]. In this work, the process of designing the bandpass filter was explained, starting from the modeling of low loss multilayer CPW lines up to miniaturizing the bandpass filter using meander resonators in order to realize the compactness of the bandpass filter operates at 28 GHz.…”

Bandpass filters for millimeter-wave band applications are typically designed using resonators. However, the design of a multilayer coplanar waveguide (CPW) monolithic microwave integrated circuit (MMIC) bandpass filter for 5G millimeter-wave band, n257 with operating frequencies from 26.5 to 29.5 GHz is still not available. Therefore, in this work, a compact bandpass filter for 5G millimeter-wave application was designed with multilayer CPW MMIC bandpass filter based on a meander resonator. The meander resonator of the bandpass filter was designed using low-loss multilayer CPW lines. In designing the bandpass filter, the resonator length and perturbation was utilized to optimize the resonance and bandwidth, and meander resonator was used to miniaturize the bandpass filter. As result, a compact bandpass filter with size of 0.75×0.75 mm<sup>2</sup> for 5G millimeter-wave band n257 was achieved. It has bandwidth of 3 GHz, an insertion loss of -2.87 dB and a return loss of -11.1 dB at frequency 28 GHz.

“…A meander structure is a very popular construction that allows for keeping the same length of a signal's traveling path while reducing the overall area of the PCB [10]. Meander structures are used in many different microwave devices: antennas [11], antenna arrays [12], phase shifters [13], filters [14], resonators [15], traveling wave tubes [16], delay lines [17], and others.…”

Multilayer meander structures for wireless communications are presented in this paper. The miniaturization of meander structures is solved by positioning the meander conductor in multiple layers. The influence of the increasing number of layers and connecting vias on the operational parameters of the meander structures is investigated. Three-dimensional models of the meander structures are designed and analyzed in the CST Microwave Studio© software package. The general mathematical model of the meander structure is presented. The computer-based simulation is verified by a physical experiment and analytical calculations. The investigation shows that it is possible to miniaturize the meander structure by placing it into different layers and connecting the meander conductors with vias. The overall length of the meander structure is decreased by 48% from 16.24 mm to 8.4 mm, while the delay time td is changed only by less than 3.2% and increased till 1.145 ns, which is 35 ps. The overall dimensions of the miniaturized meander structure are 8.4 × 17.35 × 0.76 mm. The designed structure is suitable for operation at a 2.4–2.5 GHz ISM frequency band.
