Antenna coil simulation using CST microwave studio

Hallo Every,
I am designing coil antenna on PET substrate using cst microwave in the frequency domain but I am having always problem in the port description. Could anyone tell me which port is suitible for the my structure " I am using now discrete port sparameter port" knowing that the dimensions of the coil are:
square shape 30 mm* 30mm , the space between the lines is 1 mm, the width of the line is also 1 mm. I attached the picture of the my problem please if any one can help me I will appreciate that. thanks for your help in advance
the frequwncy range is from 125 khz to 30 mhz.

i think you should reduce the space .. upto 0.7 or 0.5 mm

thank you very much Mushahid "watcher :)" I reduced already the space but nevertheless, the meshing was successful but I got this error: Could not find PEC wires adjacent to the discrete port 1 I hope you can help me in this case I t is really an emergency

o.k i would try to simulate it and let see if i could ?

Thanks in advance :) I will be very happy if you will do it

Hello again,
in the attachment you will find the cst file, may be it will help you to find the error soon.

thanks bro for this :( .. but i still can't figure out too if you would find some way pls share it wid me too
