有限接地结构上的开关寄生微带天线具有连接到小的圆形接地平面的导电套管，控制垂直辐射方向。天线的设计使用遗传算法和有限元（FEM）求解器。在1.575 GHz时，所构造的天线表现出10.7 dB的前后比和6.4 dBi的增益，与水平无仰角。天线的切换寄生性质允许其通过方位角中的5个位置来操纵定向波束。从0/spl λ/增加到0.45/spl λ/，观察到套筒线性地降低主瓣仰角，而对其它天线特性（例如增益和S/sub 11/）几乎没有影响。
A switched parasitic monopole antenna on a finite ground structure with a conductive sleeve attached to a small, circular ground plane controls the vertical radiation direction. The antenna was designed using a genetic algorithm and finite element (FEM) solver. At 1.575 GHz, the constructed antenna exhibited a front to back ratio of 10.7 dB and gain of 6.4 dBi with no elevation from the horizontal. The switched parasitic nature of the antenna allowed it to steer a directional beam through 5 locations in the azimuth. Incremented from 0/spl lambda/ to 0.45/spl lambda/, the sleeve was observed to linearly depress the main lobe elevation with little influence on other antenna characteristics such as gain and S/sub 11/.
