Hi
I is possible to design a array of rectangular patch antenna at 35 Ghz?
if so can suggest me the material, dielectric constant and substrate thickness for it??
Thanks in advance

Hi,
I am designing a single rectangular patch antenna . the substrate is Fr4 and its dielectric constant is 4.4. I have used Inset feed for the antenna.
The frequency is 2.4Ghz. I obtained the following results.
My resonant frequency(Rf) is 2.399Ghz
return loss @ Rf is 40 db
There are...
Hi,
I am designing a single rectangular patch antenna for 2.4Ghz. i am using inset feed. I used the std formulas available in Balanis to cal the length and width of rectangular patch.
The length = 30mm, width=38mm, Er=4.4,height of substrate(fr4)=1.6mm. The feed width was 0.5mm.
I am using...
Hi,
Happy new Year Sir.
I am designing a 4X1 microstrip patch antennae and the input impedance offered by each is 100 ohms. I am using a corporate feed and the source impedance is 50 ohms. I am referring Balanis for the design.But it is not very detailed
Can u suggest some good papers or...
Hi,
Thanks Tyassin, that was useful.
I have another doubt.pls help me with that also.......
Also ,If u could help me with some material for this corporate feed design it would really be useful....
Thanks in advance

Hi,
i wanted to match a complex impedance antenna using a quarter wave transformer to 50 ohm feed. It has been given in Balanis that
Then what is the impedance of the line btw the quarter wave transformer and antenna i.e, along the length So???
thanks

hi...
This post was very useful...
I am a newbie to verilog. Is it possible to use "if statement " inside generate ??????? I tried to use , i am getting the error " Illegal reference to genvar i".
This is my code..
The variable "txrx" is output of another module.
Hi
Can some one clearly explain how Quadrature coupler works?
Why is the reflected signal from port2 not coupled to port1
I referred the following site. I didnt understand the equ in the fourth dia..which explains how the reflected signal becomes 0
also pls provide with better articles...
Why do we always go for N point DFT. Why not the points taken be less than N say N-2?
Does the reason for this question has an important Analogy with any of the signal processing algorithm?
hai
For a system "with feedback" I have both gain and phase crossover frequency.
My question for this given system to be stable which one ( gain cross over frquency or phase cross over frequency) should be greater?
Also Pls explain me why that should be greater?
Thanks
