What is 应用于电小接收天线的非福斯特匹配网络研究 任仪 about?
The document presents a study on a non-Foster matching circuit designed to enhance the performance of electrically small receive antennas. By utilizing a grounded negative impedance converter based on operational amplifiers, the circuit achieves wideband matching from 10 MHz to 20 MHz, improving the receive gain significantly. Test results demonstrate the feasibility of this approach, with input impedance matching to 50 Ω and a gain improvement of over 2.5 dB.
