    T junction microstrip filters

    Hello guys! Does anyone know where i can find some issues about T-junction filters? I'm working on them and i would really aprecciate any help! Thank you so much ---------- Post added at 08:23 ---------- Previous post was at 08:21 ---------- If possible, just the basics of this type of...

    [SOLVED] microstrip impedance matching

    Sandesh, unfortunately, none of my tries gave me good results...In HFSS always when i try to match circuits with microstrip lines, the s11 parameter goes wrong (-8dB, maximum -15dB). Only when i use inset fed patches directly to the waveport provides me something useful.. Thank you so much for...

    incorrect S11 results- microstrip transmission line in HFSS

    I had the same problem and i tried everything i know to fix it, but nothing... Does ADS have a better performance than HFSS?

    dual band matching circuit

    Hey guys, I need to build two different retangular inset-fed patches (each one with its own resonant frequency) and associate then, by 100Ω microstrip lines, to a 50Ω line (two 100Ω parallel lines). What frequency must be used to determine the 50Ω line width (and lenght)? ---------- Post added...

    [SOLVED] microstrip impedance matching

    Sandesh, i checked this, is ok! Thank you so much Jayce, i'll try this! But i have a segond question too: in this project, i'm building a matching impedance circuit for 2 different inset-fed patches(1.2Ghz and 1.8GHz) using the same feed line structure, e.g., each patch is connected to a Zo line...

    [SOLVED] microstrip impedance matching

    Hi, i'm designing some microstrip antennas and i have some questions...First, i'm using an inset-fed retangular patch ready for 50ohm and i need to match it to a 100ohm microstrip line. Using the tool Microstrip Patch Antenna Calculator on emtalk.com i found that for the 100ohm line the width...

    Microstrip filters - dimensions

    Hi, i'm a beginner on microstrip design and i was trying to design a microstrip filter. Using some equations, i almost did it, but i don't know about the "lenght" that i must use between the filter itself and his feedin' ports! i searched it in a lot of books, and nothing. Some help? Thanks.
