论文摘要

这项研究提出了由与基于晶体管的非偏置相变的相位梯度贴片辐射器组成的非偏置梁置式阵列天线。这种天线表现出用于传播和接收状态的不同光束。拟议的阶段阵列天线为传输和接收状态提供了功率扩增,这在大多数实际应用中至关重要。此外,与最近提出的时间调节的天线相比,提出的非偏置梁式阵列阵列天线没有引入不希望的时间谐波和不需要的频率转换,不需要射频频率偏置信号。此外,非偏置阶梯式阵列天线很轻巧,并且适合集成电路制造。通过更改晶体管的直流电流(DC)偏置和被动相位变速器的相位,可以轻松调节传输和接收光束角,光束形状和功率扩增水平。预计这种非偏置梁置换式阵列天线将找到军事和商业应用。

This study presents a nonreciprocal-beam phased-array antenna constituted of phase-gradient patch radiators integrated with transistor-based nonreciprocal phase shifters. Such an antenna exhibits different beams for transmission and reception states. The proposed phased-array antenna provides power amplification for both transmission and reception states, which is of paramount importance in most practical applications. In addition, in contrast to the recently proposed time-modulated antennas, the proposed nonreciprocal-beam phased-array antenna introduces no undesired time harmonics and unwanted frequency conversion, requires no radio frequency bias signal. Furthermore, the nonreciprocal phased-array antenna is lightweight and is amenable to integrated circuit fabrication. The transmission and reception beam angles, the beam shapes, and the power amplification level may be easily tuned by changing the direct current (dc) bias of the transistors and phase of the passive phase shifters. Such a nonreciprocal-beam phased-array antenna is expected to find military and commercial applications.
