I have read some docs to create wifi antenna on PBC itself.
How can I increase gain level in PCB antenna???
Yes, you are correct. I am making RFID LF antenna for 125KHz. I have made coil antenna in square shape. Its size is 35mmX25mm. Its with 900uH inductance and 21Ohm resistance. Once I tried with increasing antenna dimensions with same Inductance(900uH) and resistance(21Ohms). At that...
How to calculate resonant frequency for RFID?
How inductor and capacitor values are set? How Q factor affects antenna performance and RFID detection for card? For good performance of 125KHz LF and 13.56Mhz RF what should be the Q factor value? Please provide suggestion or document...
In my board I am facing issue of radiation emission of particular 74.25MHz frequency harmonics of 7th number and getting maximum radiation on 520Mhz. Trace length is about 2168 mils and having ground plane on second layer. I have tried by putting RC filter as well putting bead also...
My confusion is I have made LF antenna for 125KHz with inductance 850-900uH and 20Ohms. Antenna terminals are directly connected Module which provides frequency.
My confusion is can I increase range of LF antenna by with decreasing Resistance??? Without making change in Inductance???
