Demand of antennas those possess wide radiation bandwidth while operating in S-band for wireless communication systems is increasing day by day. Thick substrates are popular solution to achieve wideband but they lead to frequency shift and suffer from limited gain. A potential technique to overcome the issue is to integrate an artificial magnetic conductor (AMC) between dielectric layers of a probe-fed thick substrate antenna as proposed in the paper. A parallel plate capacitor is incorporated to compensate impedance mismatch due to inductive probe. An operating band of 340 MHz is observed between 2.24 and 2.58 GHz for a gain greater than 0 dB while antenna exhibits a peak gain of 6.7 dBi. The proposed low profile AMC integrated hexagonal antenna is easy and economical to fabricate using multilayer printed circuit boards. The square loop AMC is analyzed with different inner widths to estimate the band stop frequency in both TE and TM modes. The phenomenon observed in presence of AMC during design and simulations of S-band antenna are validated with experimental results.

在无线通信系统中以S波段运行时，拥有宽辐射带宽的天线的需求正在日益增加。厚基板是实现宽带的常用解决方案，但它们会导致频移，并且增益受限。解决该问题的一种潜在技术是将人工磁导体（AMC）集成到该论文中提出的探针馈送厚基板天线的介电层之间。并入了一个平行板电容器，以补偿由于感应式探头引起的阻抗失配。在2.24和2.58 GHz之间观察到340 MHz的工作频带，增益大于0 dB，而天线的峰值增益为6.7 dBi。所提出的薄型AMC集成六边形天线使用多层印刷电路板制造起来既容易又经济。用不同的内部宽度分析方环AMC，以估计TE和TM模式下的带阻频率。实验结果验证了在S波段天线的设计和仿真过程中AMC存在的现象。
