New modified microstrip bandstop filter with only one (first order) bandstop

2009 9th International Conference on Telecommunication in Modern Satellite, Cable, and Broadcasting Services, 2009
In this paper, a new structure with only one (first order) bandstop is reported. A simple trapezoid shape of the microstrip line is introduced instead of the more complicated pattern. It obtains simple simulation, optimization and fabrication.

Novel compact microstrip interdigital bandstop filters

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004
A novel compact microstrip interdigital band-stop filter is designed and implemented. The structure is similar to that of an interdigital capacitor. The input port and output ports are connected to form the bandstop characteristic. This proposed filter with microstrip interdigital geometry not only exhibits good bandstop characteristics and a tunable ...

L-resonator bandstop filters

1996 IEEE MTT-S International Microwave Symposium Digest, 1996
A design procedure is presented for TEM narrow bandstop filters using L resonators, which are intermediate of the gap- and parallel-coupled resonators typically used, having parallel coupling only over a portion of the resonator length and a grounded end in either the coupled or stub portion of the resonator.

Absorptive planar bandstop filters

2019
A simple and very effective way to realize narrowband and wideband absorptive band stop filters (ABSFs) is presented. Analytical design equations are established to allow the direct synthesis of ABSFs according to the desired specifications. Good stopband rejection, low input reflection coefficient, and high level of input power dissipation within the ...

A Tunable Bandstop Filter Based on Source Follower

2019 IEEE 62nd International Midwest Symposium on Circuits and Systems (MWSCAS), 2019
A tunable bandstop filter based on source follower is presented. The filter is designed using a source follower architecture with partial positive feedback and feed-forward paths using 0.18µm CMOS technology. The filter consumes about 1.4 mW from a 1.8V power supply, and it is designed to have 1.5GHz center frequency with 360 MHz bandwidth and 80 dB ...

The reentrant wideband bandpass/bandstop elliptic filters

2010 10th International Conference on Actual Problems of Electronic Instrument Engineering APEIE-2010, 2010
This paper presents a novel wideband bandpass/bandstop filter configuration. The new filter is based on the reentrant structure with unequal dielectric constants of the internal and external filling. As a result, additional symmetrical transmission zeros are generated at the lower and upper stop bands of the bandpass filter leading to elliptic function

A novel wideband bandstop filter

Microwave and Optical Technology Letters, 2009
AbstractA novel bandstop filter using star shape structure is designed, fabricated, and measured. Parameters are optimized via numerical simulations. Measurements are carried out using network analyzer. The proposed filter has wide bandwidth, compact dimensions, easy fabrication, and low cost.

Bandpass and bandstop recursive filters with low sensitivity

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1986
In a sharp cutoff bandpass or bandstop recursive digital filter, the poles and zeros are expected to be clustered around the band edges, and in close proximity of the unit circle in the z-plane. Implementation of such filters with low sensitivity could be achieved by cascading second-order sections, with appropriate low sensitivity structures chosen ...

Bandpass (bandstop) digital filter design routine

Review of Scientific Instruments, 1978
As a complement to the design methods for low pass digital filters previously published [Rev. Sci. Instrum. 48, 1447 (1977)], we present a description of a bandpass (or bandstop) digital filter design program, a demonstration of its use, and the fortran code.
