First-order reflectionless lumped-element lowpass filter (LPF) and bandpass filter (BPF) design

2016 IEEE MTT-S International Microwave Symposium (IMS), 2016
This work presents design methods for first-order reflectionless lumped-element lowpass and bandpass filters. Each of the proposed filter structures contains an impedance matching circuit that can theoretically cancel out the reflected wave. We have derived the analytic design equations so that the reflectionless filters can be designed without using ...

Electromagnetic periodic structure bandpass filter (EPS‐BPF) with two transmission zeros

Microwave and Optical Technology Letters, 2004
AbstractIn this paper, an improved electromagnetic periodic structure bandpass filter (EPS‐BPF) is designed and analyzed, and its equivalent circuit is also presented. The proposed structure achieves two transmission zeros on both sides of passband, while a good rolling skirt is obtained as well.

A Novel S-Band Bandpass Filter (BPF) with Extremely Broad Stopband

2018 48th European Microwave Conference (EuMC), 2018
This paper presents a new compact wideband bandpass filter (BPF) with an extremely broad stopband consisting of two parallel coupled-line sections and multiple open-ended stubs, for S-band applications. Due to symmetry of the design, even- and odd-mode analysis method is applied to analyze the proposed filter structure.

Compact slow-wave millimeter-wave bandpass filter (BPF) using open-loop resonator

2016 21st International Conference on Microwave, Radar and Wireless Communications (MIKON), 2016
A compact slow-wave millimeter-wave bandpass filter for wireless communication systems is developed and proposed in this paper. The filter is based on an open-loop resonator that is composed of a microstrip line with both ends loaded with folded open stubs. The folded arms of the open stubs are utilized to increase the loading capacitance to ground. In

A Novel Ultra-Wideband (UWB) Bandpass Filter (BPF) With Pairs of Transmission Zeroes

IEEE Microwave and Wireless Components Letters, 2007
A novel, compact, and highly selective ultra-wideband bandpass filter was developed on a microstrip line and presented in this letter for use in wireless communication applications. The basic filter is composed of five short-circuited stubs separated by nonredundant connecting lines that contribute to the filter selectivity as well.

Millimeter-wave ultra-wideband (UWB) bandpass filter (BPF) using microstrip parallel coupled lines

2016 IEEE Wireless Communications and Networking Conference, 2016
A compact millimeter-wave bandpass filter for automotive radar systems is developed and proposed in this paper. The filter is designed to select the UWB spectrum (2229GHz) to meet the FCC specifications. The filter consists of two of parallel-coupled line sections that are quarter-wavelength long at a center frequency of about 25.5 GHz.

A carrier-burst transmitter implementation: Design of bandpass filter and amplifier-BPF connection

2012 Workshop on Integrated Nonlinear Microwave and Millimetre-wave Circuits, 2012
The importance of the bandpass reconstruction filter, BPF, in the proper operation of carrier-burst transmitters is widely accepted. However, it is often analyzed as if it could be considered isolated from the other system's components. To fill this gap, this paper presents a detailed study of the carrier-burst transmitter BPF, addressing both its most

Compact cascaded quadruplet bandpass filter (CQ-BPF) using folded loop resonator with via-hole

2011 IEEE International RF & Microwave Conference, 2011
A compact cascaded quadruplet bandpass filter (CQ-BPF) using short-circuited loop resonators is proposed for size reduction. The short-circuited loop has a resonance at a half wavelength by utilizing a via-hole and is modified to a folded structure to reduce a loop size.

Power distribution to multiple implanted sensor devices using a multiport bandpass filter (BPF) approach

2014 IEEE MTT-S International Microwave Symposium (IMS2014), 2014
This paper presents a magnetically coupled bandpass filter (BPF) approach for power distribution to multiple implanted devices. The BPF design approach accounts for the multiple loads and enables maximum power transfer into each individual receiver for given coupling coefficients between the coils.

High frequency performance and compact LTCC bandpass filter (BPF) with three transmission zeros

2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE), 2017
In this paper, a design of compact LTCC bandpass filter with three layers and three Transmission Zeros (TZs) is proposed, which obtain a high skirt selectivity with narrow passband and wide stopband. The mixed Electric and Magnetic (EM) coupling and Source-Load (S-L) coupling are utilized to create TZs in this design.
