摘要:
对于基于负阻抗变换为基础而设计的有源接收天线,具有较高的接收灵敏度和理想的天线高度;但是由于负阻抗变换是一种正反馈,致使天线的稳定性变差,因此采用宽带低噪声可变增益放大器和深度负反馈电路的结合来改善天线稳定性,并通过仿真和实验来给予验证.实验结果证明,通过加入可变增益放大器,基于负阻抗变换的有源接收天线具有高稳定性、高灵敏度和低噪声等特性,从而最终实现一个性能优良的有源接收天线.
Abstract:
An active receiving antenna based on negative impedance convertor has a high receiver sensitivity and ideal antenna height. Because negative impedance convertor is a real positive feedback, the stability of the antenna is spoiled, the broadband lownoise variable gain amplifier and negative feedback circuit are used to improve the stability of the antenna. The simulation results verify that the designed active antenna based on negtive impedance convertor with a variable gain amplifier has some advantages such as high stability, low noise and high sensitivity, etc., and therefore is an antenna with good performance.
