Try simulating this one with Pspice or Electronic workbench. The "lower" end of the strip is grounded. The bottom of the PCB is all ground. The specific dimensions depend on the dielectric but generally the wider the "vertical" part and the closer to the ground is the connection with in/out,the narrower the bandwidth. The limit is set by the lo

or this book "microstrip filters for RF/microwave applications". This is by a guy called Lancaster. You can also search for articles on him. He and his group makes a lot of compact filters. Regards
hi guys I'm dealing with a project to design an ultra-small microstrip bandpass filter in which the filter is preferably square-shaped with dimensions 27-30mm?.The PCB substrate is Duroid (er=2.5) and I'm using ADS( Agilent Advanced Design System) as simulation tool.The filter is designed for Ku band (...)
i need to design a microstrip bandpass filter for Ku band frequency range the resonant frequency is designed at 12.5GHz while the bandwidth should be in the Ku range 11.7-14.5GHz my question is does the PCB substrate FR-4 suitable for designing microstrip filters for high frequency range that i would be (...)
You may reference this book microstrip filters for RF Microwave Application (Jia-Sheng Hong & Lancaster). There is one special chapter for the miniature microstrip bandpass filter.
You can use also intedigital or combline microstrip filter, because of the fractional bandwidth≈0.21
Hi There are many books on this subject: here are some microstrip filters for RF/Microwave Applications by Lancaster Microwave engineering by Divid Pozar Regards

Dear all, I had simulated a microstrip bandpass filter using Ensemble, and three poles were obtained in the passband. So, can anyone tell me the method to determine the number of poles of a bandpass filter? Thx a lot... Best rgd!!!
what material is best or suitable to design it, if i design bandpass filter using stepped impedance resonator)SIR for bluetooth application. And also why SIR is better than UIR?
If bandpass filter for frequency F is successfully tuned, so PCB layout size after fabrication is final lenght that works without cutting or adding copper, can the same filter for halve F/2 or double F*2 frequency be made just by halving/doubling microstrip lengths in layout? Or there is a possibility, that this thing scales (...)
I never cease to be amazed at the variety of filter topologies hiding within ADS... I haven't used this one before! I believe the one you're looking for is the "CMfilter" ( ), which hides in the "Passive circuit DG - microstrip circuits" component palette.
I m trying to design a 5th order microstrip combline bandpass filter in ADS.but i don't know the component used for designing a combline filter in ADS.the combline have direct ground connection at one end and capacitor grounded at the other end. so,pls anyone let me know the exact component for designing the 5th order (...)
I've designed a microstrip bandpass filter in range 3.2-3.9 GHz using ADS. The substrate is FR4 (Er=4.7,tand=0.01,h=1.6mm). The simulation run ok and everythinng seemed to be ok. But when I built the filter and started to measure I discovered few strange things. First, the whole filter response was shifted (...)
Hello everybody!! I need to design a tunable bandpass filter 910-1150MHZ center frequency and 20MHz bandwidth to included in a bigger design. I haven't been able to find many articles-white papers-books or former design in the web. Could please anybody help me, ideas, papers, resources???? The idea is quite clear, suppose coplanar or (...)
Hi I to had to design such a filter a year ago. I can tell you that there is no "cookbook" like when you design low, -high or band pass filters from Pozars book. I can recommend articles escpecially from M. J. Lancaster. He has also written a book called "microstrip filters for RF/microwave applications" which could be (...)
Recently I designed a microstrip BPF at this freqency using Taconic RF60A (Er=6.15. loss tangent=0.0018), which is quite good for both size and performance.
well there's many implementations depending on your specs and applications like coupled lines capacitive gaps zigzag filters hairpin resonators filter and comblines read pozar and mathaei for background also microstrip filter jia sheng hond and lancaster or if you need a fast design try the ADS design guides
USE die-electric resonator methods as microstrip circuits are wide band in nature.

Use Tools > LineCalc > Start LineCalc and select Component MCLIN (for microstrip) or SCLIN (for stripline and enter the required substrate parameters and frequency on the left. Then in the center you can either enter W, S and L and analyze the structure to get ZE, ZO, Z0 etc. or enter ZE, ZO, Z0, etc. and synthesize the structure to get W, S and L.

The references are too simple. Anyone give me an example in detail?? :?: :?:
Hi I have to design a passive bandpass filter. I need to do it with the Cauer synthesis. ( i.e ladder network with R and C's). We have to take incount that the source and the load are non-ideal. So the formulas off the transfer function Z21/1+Z11 change into a much more difficult one. Does anybody knows a software tool who can synthese th

Hello, I would like to share information about this topic " MEMS bandpass filter for RF tranceiver" I have read a lot of papers that talk about the advantage of utilizing MEMS filters in modern RF tranceiver instead of the off chip SAW and crystal filters. I think we can say there are 2 types of MEMS (...)
Hi guys, I wanna to design a bandpass filter of bandwidth = 1kHz, i wants the center frequency to be able to shift about. For example, i can tune it to fc of 2kHz (BW=2.5kHz-1.5kHz = 1kHz) and later i wanna to set the fc to 5kHz. How should i do if i am only using the RC circuit. Which means that i wanna the center frequency be able to shift
ok,, this might sound stupid, but i have the following situation,,, i want to design a bandpass filter, and im using a general purpose op amp, it looks just like the filter here problem is when i power up the op amp in the filter, the output is always
