摘要

ESPAR天线通过无功阻抗的变化来引导波束，在这里，我们已经模拟并随后设计了硬件，用于将波束转向所需的最大值方向，并将零向最大干扰方向放置。在HFSS版本12中对天线进行仿真，只有中心单元是有源的，中心单元被负载变容管的6个寄生单元阵列包围。硬件结果在消声室中测量，theta和phi在指定方向上获得8db增益，步长达到30度。

Smart adaptive beam forming antenna for interference minimization

ESPAR antenna steers beam by variation of reactive impedances, here we have simulated & later designed hardware for steering beam in direction of desired maxima and placement of null towards maximum interference. Antenna is simulated in HFSS version 12, only center element is active which is surrounded by array of six parasitic elements loaded with varactor. Hardware results were measured in anechoic chamber and 8 dB gain was achieved in specified direction for theta & phi and step size achieved was 30 degree.
