摘要

介绍了一种带有集成PIN二极管开关的共面波导馈电系统的开关波束盘负载寄生单极子天线阵列。天线在开路寄生元件方向的测量增益在5.1 ~ 5.6 dBi范围内。结果表明,通过改变开关的控制电流,可以使天线的主波束方向在方位面内切换。所有四种配置的反射系数都匹配在2.45 GHz。

CPW-Fed Disc-loaded Monopole Array Antenna with Integrated PIN Diode Switches
A switched beam disk-loaded parasitic monopole antenna array with coplanar waveguide (CPW) feeding systems with integrated PIN diode switches is described. The measured gain of the antenna in the direction of the open-circuited parasite element is in the range of 5.1 dBi to 5.6 dBi. It was confirmed that by changing the control current to the switches, the main beam direction of the antenna can be switched in the azimuthal plane. The reflection coefficient for all four configurations is matched at 2.45 GHz.
