摘要

提出了一种具有不同辐射方向图可重构性的微带贴片天线。该天线工作在2.4 GHz的谐振频率，由两层罗杰斯TMM4组成，相对介电常数为4.5，损耗正切为0.002。基板尺寸为100 × 116 mm2，每块基板高度为1.524 mm。结果研究了散射参数S11和由于不同组合的工作二极管的偏置引起的辐射模式。该天线可以在三种不同的波束方向和功率电平之间切换，最大增益为6.9 dB。

Microstrip antenna for radiation pattern reconfigurability

A microstrip patch Antenna with different radiation patterns reconfigurability is proposed. The antenna operates at a resonant frequency of 2.4 GHz and consists of two layers of Rogers TMM4 with a relative permittivity of 4.5 and loss tangent of 0.002. The substrate size is 100 × 116 mm2 and the height of each substrate is 1.524 mm. The results investigate the scattering parameter S11 and the radiation patterns due to different combinations of the operating diodes that are biased. The antenna could switch between three different pattern shapes with different beam orientation and power levels and achieve a maximum gain of 6.9 dB.
