    Dual band patch antenna with slot

    Yes but the problem is my 2nd resonant seen to be at 3.3 GHz. I want it to resonate at 5.2GHz and it seems far from it. Anyone have done simulation on dual band slotted patch antenna? Pls advice me on how to get the frequency resonant at 5.2GHz; what would be the best slot dimension (LxW), slot...

    Dual band patch antenna with slot

    Hello all. I have a question. Is there any tutorial on designing dual band rectangular antenna. I am working on dual band antenna, using CST, rectangular patch on FR-4, to resonate at 2.4GHz and 5.2GHz. I have tried inserting slot on my single patch (2.4GHz) but the gain keep reducing (from...

    [SOLVED] How to get rid of another resonance in 2.4 GHz rectangular patch antenna?

    Hi all, Need your tips n advise on my design. It is a 2.4GHz rectangular patch antenna, inset feed, FR-4 of er=4.3 and loss tangent 0.02. Simulate using CST MWR. It shows double resonant in the S-11 parameter. How does this happen? Is something wrong with my design? Which part of it that gets...

    How do I obtain the desired resonant frequency of 2.4GHZ microstrip?

    thanks. but what do you mean by making the patch a little bigger? to increase the width or length or both? is the inset feed length contribute to the changes? - - - Updated - - - thank you sir for your suggestion. I am required to feed the patch using inset feed. Btw how do I check if there...

    How do I obtain the desired resonant frequency of 2.4GHZ microstrip?

    I am working on designing the 2.4GHz rectangular patch antenna. How to get the resonant frequency at 2.4GHz. I've been getting 2.43GHz most of the time with return loss of -42dB. Which parameter do I need to adjust/look into? I've tried adjusting both width and length of the patch but still...
