Abstract

This work proposes an electrically tunable reconfigurable antenna array with wideband radiation and scattering modulation using a simpler structure and an easier control mechanism. A ladder-shaped patch is designed as the radiator. By inserting only one PIN diode in the middle of the patch structure, its operation can be modulated between a patch mode and a slot mode, achieving a wideband reflection phase difference of 180°±37°. A 4 × 4 array is formed using the aforementioned element, which can reconfigure its radiation and scattering modes by controlling the states of the PIN diodes. The measured results show that the proposed array exhibits a 10 dB impedance bandwidth of 20.99% with a peak gain of 14.94 dBi in the radiation mode. In the scattering mode, the phase distributions of the elements are optimized by the group search optimizer algorithm. The radar cross section (RCS) is reduced in the frequency range of 6 GHz to 20 GHz with an average RCS reduction value of 17 dB in the operating band.

具有辐射和散射调制的1位可重构天线阵列

本工作提出了一种具有宽带辐射和散射调制的电可调谐可重构天线阵列，使用更简单的结构和更容易的控制机制。一个梯状的贴片被设计成散热器。通过在贴片结构的中间插入一个PIN二极管，其工作可以在贴片模式和缝隙模式之间调制，实现180°±37°的宽带反射相位差。利用上述元件形成了一个4 × 4阵列，该阵列可以通过控制PIN二极管的状态来重新配置其辐射和散射模式。测量结果表明，该阵列在辐射模式下的10 dB阻抗带宽为20.99%，峰值增益为14.94 dBi。在散射模式下，采用群搜索优化算法对单元的相位分布进行优化。在6ghz ~ 20ghz频率范围内，雷达截面（RCS）减小，在工作频带平均RCS减小值为17db。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
