In this letter, a novel reconfigurable 0°/90° phase shifter is proposed. Compared with the conventional phase shifters, the proposed one uses fewer reconfigurable devices and becomes more compact. Two states of a meander line are used to generate the 90° phase shift, making it suitable for the 2-D beam steering 2-bit array application. A phase shifter prototype on F4B was measured to validate its design theory. Four phase states (i.e., 0°, 90°, 180°, and 270°) are realized through the combination of the phase shifter and the array radiation element. A $2 \times 4$ array working at 1.5 GHz was fabricated and measured to verify the performance of the proposed phase shifter. When different phase states are switched, the measured peak gain of the array varies from 10.6 to 11.2 dBi.

适用于二维光束转向2位阵列应用的新型可重构微型移相器

在这封信中,提出了一种新颖的可重构0°/ 90°移相器。与传统移相器相比,提出的移相器使用更少的可重构设备,并且变得更紧凑。曲折线的两个状态用于生成90°相移,使其适合于2D光束控制2位阵列应用。测量了F4B上的移相器原型以验证其设计理论。通过移相器和阵列辐射元件的组合,可以实现四个相位状态(即0°,90°,180°和270°)。一种 2美元乘以4美元 制作并测量了工作在1.5 GHz的阵列,以验证所提出的移相器的性能。当切换不同的相位状态时,测得的阵列峰值增益从10.6到11.2 dBi不等。
