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

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'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 (...)

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.

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
