Hi, anyone can plz tell me that what's the effect of creating slots in rectangular patch antenna having coax feed? which parameters would be effected? and how? Is there any criteria for creating slots? means any formulas? Plz help me:-?
Ok! thanks for the help and i have one more problem that i have seen another method in which formulas are also used but after that there is a use of trial and error method to match the impedance. i am attaching the pdf file you can see this. and even i am not getting how the value of Zin is...
yeah! exactly i have searched it alot but i am not getting satisfactory answer and the formulas that u have given i have also seen that but the problem is that if we are going to take these points from origin then yf=W/2 means that we are getting the point at the edge of patch:?: can u plz...
