Abstract

This paper presents an electronically reconfigurable dual-mode integrated beam-steering array. The core building block to fulfill the design is the reconfigurable synthesized transmission line (RSTL), whose transmission characteristic is controlled by a varactor diode as an on/off RF switch. By integrating the RSTLs to the array feed network, the proposed array is capable of, at a given frequency, switching its functionality as a beam-switching Butler matrix or a retro-directive array combined with data modulation. The switching is only dependent on the bias voltage of the varactor diodes, and the dc power consumption is very low $(\mu \mathrm{W})$. The circuit response of the feed network and the radiation characteristics of the phased array are verified experimentally.

可重构双模集成波束控制阵列
提出了一种电子可重构双模集成波束转向阵列。实现该设计的核心模块是可重构合成传输线(RSTL),其传输特性由一个变容二极管作为射频开关控制。通过将rstl集成到阵列馈电网络中,所提出的阵列能够在给定频率下切换其功能,作为波束切换巴特勒矩阵或与数据调制相结合的反向指示阵列。开关仅依赖于变容二极管的偏置电压,并且直流功耗非常低。实验验证了馈电网络的电路响应和相控阵的辐射特性。
