Hello !
I hope you guys can help me!
I wanna simulate an antena in AWR MW-Office like the antenna in the PDF-file I uploaded with this post.
Something like that:
3x3 mm, 4 x turns, conductor
thickness of 0.4 mm spacing between turns 0.4mm
Who could I do that? Maybe someone can send me an example :D
It is in the in the frequency range of 700-1200 MHz
I've been drawing tries since as below but does not work,,if someone Idea had why not go
oder wie zeichne ich das...,
Looking foward to hear from you!
Thanks anyway!
MOD - moved to more appropriate forum.

no one has time?
Hi ,
1) use logarithmic spiral as a monopol, wire 0,8mm dia about 30mm
2) see page 287, book the RF in RFID Daniel M.Dobkin where you can find the solved example of a near-fied antenna
