![]() Is it better to do so, compared with the case in question 1? Usually the antenna is tuned to be 50 ohm at the resonant frequency.For Marcus response, did you mean that once the antenna parameters are fixed as desired, e.g Zin = 50 ohm and S11 = -20 dB 900 MHz, the matching network is there, as in the above model, to translate 50 ohm to 6 - j170 ohm which is the input impedance of the rectifier? So, will the antenna performance be lower than it would be if it resonates?Įdited: Well, I guess I got my misunderstanding here. The goal of matching is to transmit/receive as much power as possible. If they do so, the antenna will NOT resonate at the frequency the antenna is matched. ![]() The authors in the paper I'm reading tried to match the antenna to that input impedance. The input impedance of the half-wave rectifier is 6 - j170 ohm at Pin = -10 dBm at the desired frequency, where Pin is the input power to the matching circuit as illustrated in the below figure. Both of them are placed in one PCB (PCB antenna). I'm about to match an antenna and a half-wave rectifier using Schottky diode.
