    Where exactly are EBG structures inserted ?

    Hi.. Can u pls tell me where exactly are EBG structures inserted ? In a Microstrip Patch antenna - are these structures etched on the Ground or Substrate or Patch itself ? Or only Substrate and Patch are etched to form EBG structures ? Or all 3. Another question: What are the criterion for...

    What kind of antenna feedline can this be called ?

    Oh.. i think its microstrip line feedline.. But what i cant understand is ... i have etched this microstrip line feedline (the horizontal line) with a certain structure that can be seen in picture1. So after i have etched it.. wat shud it be called ? Can u tell me wats a CPW ? I'm sorry but...

    Mathematical approach for feedline design

    I want to feed rectangular patch antenna using a microstrip feedline (50 ohm) What is the approach taken ? Are these the 2ways of using a microstrip feedline - 1. Inset feed ==> we find the location on the patch such that its impedance at that point is 50 ohms. And then we use the inset feed...

    Help me change the feedline distance of antenna in IE3D

    Re: IE3D To add more to my last post.. You said.. The example I show in Fast_Em.bmp is the optimized results with perfect matching at 14.75 GHz. You can change your goals and get the results in seconds. My goal is -- 1. I change the location of the feedline. 2. Goal = Impedances shud be...
