    Urgent Help! RFID Antenna Simulated in HFSS for PCB milling

    Hi, I have designed the RFID tag Bow-Tie antenna in HFSS attached**broken link removed**. My main desire is that the antenna simulated should have closer impedance value with the manufactured one after simulation. So for this purpose please check my design environment that is it correctly in...

    Question about UHF RFID antenna S11 values

    Re: UHF RFID antenna S11 Thanks Venu, I have read in the book that S11 should be between -10dB and -15dB so that antenna should not be sensitive to environmental noises. What you say about such concerns?

    Question about UHF RFID antenna S11 values

    Hi, I am designing the UHF RFID tag antenna in HFSS but the S11 of the antenna is (-30dB) at the desired frequency 915Mhz. Should I proceed with this S11? Please guide me what it represents with lower S11, I mean whats the difference between the S11=-7dB and in other case if S11=-30dB?

    Patch Antenna in HFSS

    Hi, λ/10 is minimum so no need to exceed this value but yes you can make more far away but that will just waste your computing resources. Yes the same applies to far field, that what the rule book says:) I agree with Sweetchoto.
