UWB antenna

[Admin 2545]

After you simulate, make a plot of S21 (between one port and the other) and it will give you the ratio between the power received by one antenna and the power inserted into the other one. If you simulated in one frequency only, go to the simulation information window ( HFSS>Fields>Edit Sources,,, how to define the excitation power of lumped port .) and you can see the S matrix there.

Jomy how can i design a receiver antenna to receive trasmitted power in hfss.  I have designed two identical antennas one as trasmiter and other as receiver. i need design steps required to implement the above system can you provide it.

[sandeepv 10]

I also needed design steps material to implement MIMO antenna system please provide the material for it also.

[Admin 2545]

Is your transmitting antenna and receiving antenna in the same design? If so, once the transmitting antenna is excited by port, the radiated field will excite another antenna. If you have two patches, you will excite the transmitting antenna with lumped port and another patch will have 50 ohms or whatever your terminating impedance is. 
If two antennas are in different designs, your receiving antenna can be excited by linked far field or near field source of the source antenna. If you know your magnitude of incident electric field you can use incident wave for excitation.

suppose if i have a system like as shown in the below figure what should be radiation box size ?

[Admin 2545]

 transmitting antenna with lumped port and another with waveguide port,,,,the distance between the antennas average lambda = 1,2,3 ....n...

[sandeepv 10]

What about the radiation box jomy, should the radiation box enclose both antennas or not ?

[Admin 2545]

radiation box with both antennas ,,,for nearfield

[sandeepv 10]

i have designed a mimo antenna in hfss,,,is it correct

mimo.hfss

[Admin 2545]

,,,I haven't hfss ,,,please give me cst...!!!

dear jomy .....can you kindly reproduce the result  given in base paper for return loss

[Admin 2545]

[sandeepv 10]

Dear jomy, kindly check S11,S22,S33,S44 plots also for me.

[Admin 2545]

,,,port 2,4 don't in work

[Admin 2545]

Impedance is not good...

 

[sandeepv 10]

I think we can plot the E field vector animation on the  antennas excited by either  port or port 4 in order to know whether they are working or not.

[Admin 2545]

,,look...!!!

 

[sandeepv 10]

Actually that cpw line is optimized to give 50 ohm resistance.

,,,ok,show me...!!!

[sandeepv 10]

PLease help me in this problem then i can complete my project report.

the problem you say, I do not know ..

[sandeepv 10]

almost 50 ohm

[Admin 2545]

,,,try this...

This antenna covers the common frequency of radio frequency unit such as mobile phone communication, UWB positioning module and Wifi.
