“…Other authors have introduced a cascaded two high‐ and lowpass Chebyshev cells to serve as an electrical model for micro‐machined silicon UWB BPFs [7]. To maximise rejection by generating finite transmission zeros at both sides of the filter response, a third‐order wideband Chebyshev filter has been employed with one capacitor and two inductors as additional components [8].…”

A new approach is proposed to act as an efficient design technique for the implementation of ultra-wideband (UWB) bandpass filters in integrated passive device technology. The proposed design is based on two major original contributions. First, the use of hourglass filter theory which, to the best of authors knowledge, has not been applied yet to such technology. Then, the minimisation of the number of inductors involved in the filter circuit through the zigzag technique. Implemented in 0.18 µm CMOS technology, the designed filter exhibits excellent performances such as two finite tunable transmission zeros, enhanced selectivity, a bandwidth covering the entire UWB spectrum of 3.1-10.6 GHz, a stopband rejection better than 15 dB throughout frequencies below 2.7 GHz and above 11 GHz, a good matching better than 11 dB, a minimum mid-band insertion loss of 1.8 dB and, finally, a sufficiently constant group delay. With these features and only 10 lumped elements, the proposed filter is one of the most promising compact filters for UWB applications.

“…For instance, a 3-to 5-GHz ultra-compact band-pass filter has been designed and fabricated on SrTiO 3 composite [6], and a differential embedded band-pass filter with bandwidth from 4.88 GHz to 5.65 GHz has been realized using FR-4 substrate [7]. However, few study has focused on the compact embedded VHF (Very High Frequency) band-pass filter based on the high permittivity polymer composite films.…”

Band-pass filters with low insertion loss and high frequency selectivity are widely used in the modern electric device and communication systems. With the requirement of the electrical system miniaturization, embedded filter was proposed because of its light weight and excellent performance. In this paper, a fully embedded VHF band-pass filter with bandwidth from 280 MHz to 400 MHz is designed and fabricated based on the BaTiO 3 -epoxy composite film. The filter is composed of a power plane with cross coupled microstrips and a double helical ground structure (DGS).The size of the band-pass filter is 5mm× 5 mm. It was embedded in a multi-layered FR-4 packaging substrate through the PCB manufacturing process. The measured results of insertion loss and return loss are similar to the simulated results. The measured results shows that the insertion loss is no more than 3.8 dB in pass-band and over 10 dB suppression is obtained at above 1.2 GHz, which is important for the practical application in communication. The embedded band-pass filter using BaTiO 3 -polymer film as a substrate is a new way for electronic system miniaturization.

“…However, the low dielectric constant of the substrate limits the miniaturization of the filter. To reduce the filter size and cost, much research work has been carried out including developing and utilizing high permittivity embedded functional materials [5], or designing a new structure, such as dual-mode resonator [6,7]. Dual-mode microstrip resonators which are composed of the square loop [8], square patch and loop resonators [9] have been actively reported because each dual-mode resonator can be used as a doubly tuned resonant circuit.…”

A new compact microstrip dual-mode bandpass filter with the center frequency of 2.4GHz is proposed based on embedded capacitance material (BaTiO3-epoxy composite film). The filter consists of a defect ground structure (DGS) and an open-loop step-impedance resonator with a short-circuit line in the middle of the resonator. The bandwidth of the filter can be optimized by adjusting the width of the short-circuit line. A compact prototype was fabricated by embedding the bandpass filter into a multi-layered FR-4 packaging substrate through the PCB manufacturing process. The measured results show that the insertion loss is 2.23 dB, the return loss is greater than 30dB at the center frequency 2.231 GHz. The size of the proposed single one is 1.8 mm×1.85 mm. To improve the performance of the filter, a cascaded two-stage dual-mode filter with open-loop DGS was designed, fabricated and measured based on the single dual-mode filter. The size of the prototype is 3.55 mm×1.75 mm. The measured insertion loss is less than 4 dB and the return loss is higher than 15dB at 2.58 GHz, both agreeing well with the simulated results below 5GHz. It indicates that introducing the DGS can improve the pass band characteristic, miniaturization and selectivity.
